0:00:02 > 0:00:05On Roar today the keepers are very worried about
0:00:05 > 0:00:10George, one of the park's oldest and friendliest De Brazza monkeys.
0:00:10 > 0:00:12Can the vet find out what's wrong?
0:00:12 > 0:00:15One kidney is a little bit big.
0:00:40 > 0:00:43Hello and welcome to Roar, I'm Johny.
0:00:43 > 0:00:46And I'm Rani and these guys over here are Copasoh and Lidaeng
0:00:46 > 0:00:47the Malayan tapirs.
0:00:47 > 0:00:51Did you know female tapirs actually weigh more than the males
0:00:51 > 0:00:55and the largest female ever recorded was an astonishing 540 kilos.
0:00:55 > 0:01:01Wow, that's about 4,500 of their favourite snack, the banana.
0:01:01 > 0:01:02That is one tubby tapir.
0:01:02 > 0:01:05Speaking of tubby, we've got a fat show for you today.
0:01:06 > 0:01:10Coming up, this canny crew puts ANOTHER keeper under the spotlight
0:01:10 > 0:01:13and the questions are getting pretty tough.
0:01:13 > 0:01:17- Guys, are you ready to test Joel? - Yeah!
0:01:18 > 0:01:22I find out why the margay is the only species of cat in the world
0:01:22 > 0:01:26able to run down a tree head first.
0:01:27 > 0:01:32And why are my cupcakes turning the gorilla's pooh purple?
0:01:39 > 0:01:41First though, this is George,
0:01:41 > 0:01:46one of the park's oldest and most loved De Brazza monkeys.
0:01:46 > 0:01:49He's also a firm favourite with our Roar rangers.
0:01:52 > 0:01:55We've followed this friendly monkey on Roar
0:01:55 > 0:01:56through his many ups and downs.
0:01:56 > 0:01:59Watched him be an amazing dad to five babies
0:01:59 > 0:02:01and win everyone's hearts.
0:02:03 > 0:02:06But, his poor health has been a constant concern.
0:02:06 > 0:02:11Last year, George was diagnosed with a worrying medical condition.
0:02:11 > 0:02:18He's got a condition known as diabetes which, if left unmanaged,
0:02:18 > 0:02:23could possibly kill him or make him very unwell.
0:02:23 > 0:02:25Diabetes is common in humans,
0:02:25 > 0:02:27in fact, keeper Matt has this condition too.
0:02:27 > 0:02:31It's when your body doesn't make enough insulin, which is the
0:02:31 > 0:02:34chemical the body needs to control how much sugar is in the blood.
0:02:34 > 0:02:38So, just like with humans, George eats a specially
0:02:38 > 0:02:43created diet which doesn't include too much sugary fruit.
0:02:43 > 0:02:46Each day George is injected with insulin by the primate team
0:02:46 > 0:02:49and this keeps his condition under control.
0:02:49 > 0:02:53However, recently George has been looking a bit thin and unwell,
0:02:53 > 0:02:58so today worried head keeper Simon is preparing to help Jane the vet
0:02:58 > 0:03:00knock him out so they can examine him.
0:03:03 > 0:03:05The plan today is to check on George.
0:03:05 > 0:03:09We've noticed he's possibly looking a little bit thinner at the moment.
0:03:09 > 0:03:13We want to go down there and be in a position where we can knock him out,
0:03:13 > 0:03:16have a look at him and give him a good overall check up.
0:03:16 > 0:03:20Simon has looked after George for 15 years and the two have quite a bond.
0:03:20 > 0:03:22So, Jane's given him the job
0:03:22 > 0:03:25of injecting George with the anaesthetic today.
0:03:25 > 0:03:26He's a very relaxed monkey
0:03:26 > 0:03:30and Simon has always been able to inject him in the bottom.
0:03:30 > 0:03:32I mix up the mixture in the syringe,
0:03:32 > 0:03:35give it to Simon and he injects it and George goes to sleep.
0:03:35 > 0:03:38It's always nice to get someone else to do your job.
0:03:38 > 0:03:42We hope he'll see it as an insulation injection. He might be shocked
0:03:42 > 0:03:45it's the wrong time of day but might be in a position to not overreact.
0:03:48 > 0:03:52- If you'd like to give that to George that'd be great.- Righty-ho.
0:03:53 > 0:03:56Giving any animal an anaesthetic is dangerous,
0:03:56 > 0:04:00especially if they are elderly, so the keepers and Jane are concerned
0:04:00 > 0:04:04but it's vital George has this check up to find out what's wrong.
0:04:14 > 0:04:17Right it's time for another ask the keeper.
0:04:17 > 0:04:19Come and meet head of hoof stock Joel Bunce.
0:04:19 > 0:04:22Joel is in a bit of a piggy predicament
0:04:22 > 0:04:25cos we are going to be asking him questions about the red river hog.
0:04:25 > 0:04:29- Guys, are you ready to test Joel? - Yeah.
0:04:29 > 0:04:32- Joel, are you ready to save your bacon?- Oh, yes.
0:04:32 > 0:04:36All right then. Let's fire some questions at Joel. Who's first?
0:04:36 > 0:04:38Where do hogs sleep?
0:04:38 > 0:04:40Where do they sleep? Good question.
0:04:40 > 0:04:43They tend to sleep kind of burrows, makeshift nests,
0:04:43 > 0:04:47things they've dug themselves or other animals have done,
0:04:47 > 0:04:51or they'll make a loose nest full of branches and things like that
0:04:51 > 0:04:53and they'll just sleep on that or,
0:04:53 > 0:04:55if it's a really nice sort of evening,
0:04:55 > 0:04:58they'll just sleep outside on the forest floor.
0:04:58 > 0:04:59Do they eat meat?
0:04:59 > 0:05:03They can eat meat. It's not part of their normal diet
0:05:03 > 0:05:06but if they get the opportunity to eat it they will.
0:05:06 > 0:05:09Things that have died or if they managed to catch something
0:05:09 > 0:05:13that's unlucky enough to be slow for them to get, they'll eat it.
0:05:13 > 0:05:15Pigs are what's called omnivores
0:05:15 > 0:05:18which means they'll eat meat and fruit and veg.
0:05:18 > 0:05:23- Fire questions!- Why are they called red when they're actually orange?
0:05:23 > 0:05:25Ooh!
0:05:25 > 0:05:31They are kind of a red. I know they look a bit sort of gingery orange.
0:05:31 > 0:05:34We would say it's a chestnut red.
0:05:34 > 0:05:36It's a bit of a posh thing.
0:05:36 > 0:05:40Probably in the forest, when it's a lot darker, the colour
0:05:40 > 0:05:44looks a lot darker and therefore more of a red colour.
0:05:44 > 0:05:46Are they dangerous?
0:05:46 > 0:05:50They can be dangerous, particularly mums with babies
0:05:50 > 0:05:53because she wants to protect the young.
0:05:53 > 0:05:54You might get a chance to see,
0:05:54 > 0:05:58particularly the male here has got very big sharp teeth,
0:05:58 > 0:06:03they're poking out the side there. So, yeah, they are very dangerous.
0:06:03 > 0:06:07Luckily these guys are pretty good and nice and calm.
0:06:07 > 0:06:10A wild red river hog could be very dangerous.
0:06:10 > 0:06:13Why do they have big funny ears?
0:06:13 > 0:06:17They have big funny ears, it's all part of their communication,
0:06:17 > 0:06:21it's good for hearing because the bigger the ears the more sound
0:06:21 > 0:06:24it traps so they can hear obviously quieter sounds
0:06:24 > 0:06:25and also from a further distance.
0:06:25 > 0:06:30Obviously it's all part of their facial communications
0:06:30 > 0:06:33where they communicate with movements as well
0:06:33 > 0:06:35and the ears are part of that.
0:06:35 > 0:06:39They sort of hold them out when they are inquisitive
0:06:39 > 0:06:42or even when they are aggressive as well, they hold them out
0:06:42 > 0:06:46much like an elephant, make themselves appear more fearsome.
0:06:46 > 0:06:50They've got a number of uses but they are pretty funky looking.
0:06:50 > 0:06:53My uncle has got really hairy ears, since he's got older.
0:06:53 > 0:06:56Is that what's happened here to the red river hog,
0:06:56 > 0:06:58is that why his ears are all hairy?
0:06:58 > 0:07:04No, this is a feature that all Red River hogs have, these kind of
0:07:04 > 0:07:07long sort of spindly ears with the hairs on the end.
0:07:07 > 0:07:11- But, it looks good though, doesn't it?- Do people like long hairy ears?
0:07:11 > 0:07:13- No.- I think you're on your own there.
0:07:13 > 0:07:17Joel, I've got to say you haven't faltered, you haven't stumbled.
0:07:17 > 0:07:20You know all the answers, or does he?
0:07:20 > 0:07:24I think we should have a killer question, do you all agree?
0:07:24 > 0:07:27- Yeah. - They want to catch you out, Joel.
0:07:27 > 0:07:31Come on, let's hoggle together. Hog...oh, forget it.
0:07:31 > 0:07:33THEY WHISPER
0:07:35 > 0:07:37Yeah!
0:07:37 > 0:07:39- Come on, let's hear you go yeah! - Yeah!
0:07:39 > 0:07:42OK, head of hoofs or Mr know-it-all of the red river hogs,
0:07:42 > 0:07:44we have your killer question.
0:07:44 > 0:07:46Now, remember if you get this wrong
0:07:46 > 0:07:50you'll be crying wee, wee, wee all the way home.
0:07:50 > 0:07:52Are you ready for it?
0:07:52 > 0:07:57- Yeah.- OK, then! How many male red river hogs
0:07:57 > 0:08:00would it take to weigh the same as a fire engine?
0:08:00 > 0:08:04I love the look on his face.
0:08:04 > 0:08:07I would say about 250.
0:08:07 > 0:08:11Well, I'm going to tell you the correct answer.
0:08:11 > 0:08:13A fire engine weighs around 13 tonnes
0:08:13 > 0:08:17and a male red river hog, on average, weighs 68 kgs.
0:08:17 > 0:08:20So, with my working out, that's about 191 red river hogs
0:08:20 > 0:08:24to weigh the same as a fire engine. You were nowhere near!
0:08:24 > 0:08:26So, guys, he didn't get that right
0:08:26 > 0:08:30but apart from that his answers were pretty good, I'd say.
0:08:30 > 0:08:34So, what do we think, thumbs up or thumbs down for Joel?
0:08:34 > 0:08:36Yeah!
0:08:36 > 0:08:37Look at you, Joel,
0:08:37 > 0:08:41two, four, six, eight thumbs. I'll give you one as well.
0:08:41 > 0:08:43- Well done, you.- Thanks.
0:09:02 > 0:09:06One of the last remaining species of wolf in Europe is the Iberian wolf.
0:09:06 > 0:09:09They live in a small area of hills and plains
0:09:09 > 0:09:11in north Portugal and north western Spain.
0:09:11 > 0:09:14But, sadly there are thought to be
0:09:14 > 0:09:17no more than 2,500 of these animals left in the wild.
0:09:17 > 0:09:20The good news is there is a successful breeding programme
0:09:20 > 0:09:24in place on the parks and last year five adorable cubs were born.
0:09:24 > 0:09:28Since then, Mum and Dad have gone on to have another litter
0:09:28 > 0:09:31so last year's cubs have just been moved
0:09:31 > 0:09:34to a new enclosure at their sister park.
0:09:34 > 0:09:36Head keeper Rich is really excited
0:09:36 > 0:09:40to have new animals to look after and learn about.
0:09:40 > 0:09:43- How are you doing, Rich?- Yeah. - So, where are they now?
0:09:43 > 0:09:45Well, they are in here somewhere,
0:09:45 > 0:09:47but being quite elusive and quite secretive
0:09:47 > 0:09:51they kind of hide up quite well in very little cover really.
0:09:51 > 0:09:55They can just dig themselves into a little bit under a branch
0:09:55 > 0:09:56and just stay there, very still,
0:09:56 > 0:09:59hoping we won't disturb them or no-one sees them.
0:09:59 > 0:10:01That must make the move interesting.
0:10:01 > 0:10:05I don't know how it went at the other end but when they got here,
0:10:05 > 0:10:08most of them were still quite groggy because of the knock out
0:10:08 > 0:10:10but once they came out of the crates
0:10:10 > 0:10:13they sort of sloped off a little bit but they came out very nicely.
0:10:13 > 0:10:16How are they getting on now, have you seen much of them?
0:10:16 > 0:10:19Yeah, as I say, they are quite nervous and quite shy.
0:10:19 > 0:10:23We've made a point of going in and making sure they're all OK
0:10:23 > 0:10:26and that they've come through the sedation all right
0:10:26 > 0:10:28and that there's no side effects.
0:10:28 > 0:10:31And that their eating already and drinking.
0:10:31 > 0:10:34- They seem happy.- As a head keeper, do you get nervous when a new animal
0:10:34 > 0:10:38comes to the park? Have you worked with these guys before?
0:10:38 > 0:10:41Not the Iberian wolves, but we've had quite a lot of experience
0:10:41 > 0:10:43with the timber wolves we've had here.
0:10:43 > 0:10:46It's always a little bit nerve wracking to hope
0:10:46 > 0:10:49that they'll settle in, but, yeah, it's always good as well.
0:10:49 > 0:10:51We love getting something new in,
0:10:51 > 0:10:53it just means we've got to learn from the off
0:10:53 > 0:10:57and try and work out what's best for them and how we work them and stuff.
0:10:57 > 0:10:59It looks like they've got a happy new home here.
0:10:59 > 0:11:02- Good luck helping them settle in. - Thanks a lot.
0:11:04 > 0:11:09What do you call a load of giraffes at traffic lights?
0:11:09 > 0:11:10A giraffic jam!
0:11:11 > 0:11:13Oooh-ohh-oooh!
0:11:15 > 0:11:17Why did the bull blush?
0:11:17 > 0:11:18I don't know.
0:11:18 > 0:11:21Because it saw the cow slip!
0:11:21 > 0:11:23Buckaw!
0:11:23 > 0:11:27- What do snakes learn in school? - I don't know.
0:11:27 > 0:11:28Hiss...tory.
0:11:40 > 0:11:43Over at the De Brazza enclosure, Simon is waiting
0:11:43 > 0:11:46for his favourite monkey, George, to fall asleep
0:11:46 > 0:11:49from the anaesthetic he's just injected him with.
0:11:49 > 0:11:53It usually takes about five minutes for the drug to take effect
0:11:53 > 0:11:57and once he's out, vet Jane can give him a check up.
0:11:57 > 0:12:01As you can see he is getting a little bit more wobbly.
0:12:01 > 0:12:04I don't want him to fall off the branch and hit the floor.
0:12:04 > 0:12:08I want to be able to catch him...just in case he starts to go.
0:12:08 > 0:12:13We are just waiting for him to actually fall asleep really.
0:12:13 > 0:12:17He's nearly there but not quite, not given up the ghost yet.
0:12:17 > 0:12:20This tough De Brazza is a fighter
0:12:20 > 0:12:24and in typical George fashion, he's refusing to go to sleep.
0:12:24 > 0:12:26I would expect him to sleep quite quickly.
0:12:26 > 0:12:29He's not really scared of us, but
0:12:29 > 0:12:32it takes longer. It shows you each animal is different and
0:12:32 > 0:12:36you should never be complacent cos they will surprise you.
0:12:36 > 0:12:41At last George is sleepy enough to be handled.
0:12:41 > 0:12:46Let's sit you there a second, there you go. He's not quite out of it.
0:12:46 > 0:12:50But some of his family are intent on waking him up again.
0:12:53 > 0:12:54Out, both of you.
0:12:57 > 0:13:00Simon covers George with a towel to stop him being distracted
0:13:00 > 0:13:02and to help him fall fully asleep.
0:13:03 > 0:13:07He's sedated so we'll transfer him I think.
0:13:07 > 0:13:11And the trick works, George is almost asleep
0:13:11 > 0:13:17and in a few moments the team will be able to begin his vital check up.
0:13:39 > 0:13:42Have you ever wondered if gorillas get bored eating
0:13:42 > 0:13:44the same veggies day in day out.
0:13:44 > 0:13:45I did and that's why I popped
0:13:45 > 0:13:49into the Roar kitchen and helped bake some tasty beetroot muffins.
0:13:49 > 0:13:53- Hiya.- Hello.- Matt, you said the gorillas wanted beetroot.
0:13:53 > 0:13:56So, I've made beetroot muffins.
0:13:56 > 0:13:58- Does that look tasty or what? - Very impressive.
0:13:58 > 0:14:01I've got to ask though, beetroot for the gorillas, why?
0:14:01 > 0:14:04Well, first of all it's nice to give
0:14:04 > 0:14:08them lots of different variety of foods but beetroot is a good source,
0:14:08 > 0:14:11high in vitamins and minerals, vitamin C, iron
0:14:11 > 0:14:15- and it also lowers blood pressure. - So they are really healthy then.
0:14:15 > 0:14:18How are we going to give this to them, maybe with a cup of tea?
0:14:18 > 0:14:21Possibly with a cup of tea, but we generally just go in
0:14:21 > 0:14:24and scatter the food around for them.
0:14:24 > 0:14:26There might even be one left over for me.
0:14:26 > 0:14:28Come on then, Matt, let's get scattering.
0:14:36 > 0:14:39I'll hide one just here, there we go.
0:14:39 > 0:14:42Nobody stand on it. Please don't stand on the cake.
0:14:42 > 0:14:44Maybe some near the water.
0:14:44 > 0:14:46I'll put some of this beetroot down here.
0:14:46 > 0:14:49The other question is, I like beetroot, a bit personal this.
0:14:49 > 0:14:52Sometimes when you have beetroot it can make
0:14:52 > 0:14:56your pooh and wee come out purple, does that happen with gorillas?
0:14:56 > 0:15:00- It certainly does, yeah. - Does it?- Yeah, it's the same.
0:15:00 > 0:15:04Every morning after we've given them beetroot we clean up purple pooh.
0:15:04 > 0:15:08I tell you we won't be coming to see that then, that's for sure.
0:15:08 > 0:15:12That's your next job tomorrow morning, you're back in.
0:15:12 > 0:15:14I don't think so. I don't think so, Matt.
0:15:14 > 0:15:17Join us later on when we release the gorillas and find out
0:15:17 > 0:15:21if they go bonkers for our buns. Come on, Matt, take a bite.
0:15:21 > 0:15:22They're tasty! Mmm.
0:15:35 > 0:15:38Some of the most elusive animals in the park
0:15:38 > 0:15:41are the small cats and there are some we hardly
0:15:41 > 0:15:45ever get the chance to see on Roar. One camera-shy cat is the Margay.
0:15:45 > 0:15:48These wild cats come from the rainforests
0:15:48 > 0:15:53of Central and South America and lucky me is about to meet one.
0:15:56 > 0:16:00The reason I'm whispering is because I've popped down to
0:16:00 > 0:16:02the margay enclosure in the hopes of glimpsing
0:16:02 > 0:16:05one of the park's most elusive small cats.
0:16:05 > 0:16:08In there is keeper Steve Veen who's got an idea.
0:16:08 > 0:16:10What's up your sleeve, Steve?
0:16:10 > 0:16:13Johny, I've got myself a little quail here,
0:16:13 > 0:16:17- which I hope is going to tempt her over.- Really?
0:16:17 > 0:16:22- I am going to place it on the branch above me.- She's quite a good climber?
0:16:22 > 0:16:24Fantastic climbers.
0:16:24 > 0:16:27They are one of the most acrobatic species of cats.
0:16:27 > 0:16:29They can swivel their ankle joints 180 degrees
0:16:29 > 0:16:32so they can run head first down a tree.
0:16:32 > 0:16:34They're amazing. It's fantastic.
0:16:34 > 0:16:39They are able to chase squirrels and small monkeys through the tree tops.
0:16:39 > 0:16:41Would you say they are good hunters?
0:16:41 > 0:16:44Very good hunters, but they hunt at night,
0:16:44 > 0:16:50- so you hardly ever see them. - Steve, look she's coming.- Yeah.
0:16:50 > 0:16:53- How do you think that she's knows it's there?- She's seen me,
0:16:53 > 0:16:57so she knows something's up. She's so used to me feeding her
0:16:57 > 0:16:59that's all she ever associates me with is food.
0:16:59 > 0:17:03Really. How about in the wild how would she go about hunting,
0:17:03 > 0:17:04would she use her ears or her eyes?
0:17:04 > 0:17:08They've got fantastic eye sight, but they do hunt at night.
0:17:08 > 0:17:12Their night vision has to be pretty good and it is.
0:17:12 > 0:17:15She has got very big eyes in comparison to the size of her head.
0:17:15 > 0:17:17Their hearing is fantastic as well.
0:17:17 > 0:17:21So, she'll be listening out for little rustles and leaves
0:17:21 > 0:17:24or anything like that which might be an indication there's an item of
0:17:24 > 0:17:28food running around which she can get hold of. Are you going to come over?
0:17:28 > 0:17:32Other than her eyes, Steve, she looks quite like a...
0:17:32 > 0:17:35cat you would find at home, how else is she different?
0:17:35 > 0:17:38Size-wise they are very similar,
0:17:38 > 0:17:42but their coat pattern is completely unique.
0:17:42 > 0:17:45You won't see any pet cats looking like that.
0:17:45 > 0:17:48- No.- Stunning.- It's beautiful. - She is absolutely beautiful.
0:17:48 > 0:17:52That's posed a big problem for the species in the wild.
0:17:52 > 0:17:55It means they've been hunted a lot.
0:17:55 > 0:17:57Their numbers have been declining rapidly.
0:17:57 > 0:18:04Within just 30 years, the fur trade has caused them a big, big problem.
0:18:04 > 0:18:07You can see such a beautiful coat it's no real surprise that people
0:18:07 > 0:18:09want to see these animals.
0:18:09 > 0:18:12She took that gently, that was amazing seeing her take that.
0:18:12 > 0:18:16I was expecting her to kind of leap at it a little bit more.
0:18:16 > 0:18:19- Why did she take it so softly? - She knows it's not going to move.
0:18:19 > 0:18:24If she tries to hand feed from me she'll snatch it off me.
0:18:24 > 0:18:25She's not shy at all.
0:18:25 > 0:18:28If it's on the branch there's no reason to just grab it
0:18:28 > 0:18:31and run off with it, she knows it's not going to go anywhere.
0:18:31 > 0:18:35Well, it was amazing to see how elegant this elusive animal
0:18:35 > 0:18:37was and to see her up close as well.
0:18:37 > 0:18:39Thank you so much for the privilege, Steve.
0:18:43 > 0:18:47Right then, gamers, are you ready for your cheat code?
0:18:53 > 0:18:55Your park should be getting nice and full,
0:18:55 > 0:18:58but don't forget to keep feeding your animals
0:18:58 > 0:19:00to keep them healthy and happy.
0:19:13 > 0:19:19I'm still wearing my pinny because earlier on myself and Matt
0:19:19 > 0:19:22placed some healthy beetroot buns inside the gorilla enclosure.
0:19:22 > 0:19:25Now, you can just see one next to the water.
0:19:25 > 0:19:29They love beetroot, but will they like them in the form of cakes?
0:19:29 > 0:19:31That's what we're going to find out, isn't it?
0:19:31 > 0:19:35- Shall we release the gorillas and see what they think?- OK.
0:19:35 > 0:19:36Need gorillas.
0:19:36 > 0:19:38So, here they come now.
0:19:38 > 0:19:41Have you put veggie down in here as well?
0:19:41 > 0:19:44Yeah, they've already got their morning forage.
0:19:44 > 0:19:46That's cauliflower and mooli.
0:19:46 > 0:19:49If we'd put the cakes out, they'd be too focused on them.
0:19:49 > 0:19:53You say cauliflower and mooli. What is mooli?
0:19:53 > 0:19:55Mooli is a type of radish.
0:19:55 > 0:19:59Just a big white radish that we give them, we chop it up
0:19:59 > 0:20:02quite small and put it in the straw. They quite like it.
0:20:02 > 0:20:05Ah, look at that, straight for my muffin.
0:20:05 > 0:20:09Oh, there you go, greedy gorilla, he's taken the beetroot as well.
0:20:09 > 0:20:12- Who's that?- That's Kouillou. He's gone for one.
0:20:12 > 0:20:17What they'll often do is they'll take as many as they can basically and
0:20:17 > 0:20:20then just go off somewhere and eat it in peace and quiet.
0:20:20 > 0:20:23They can't really mess around with the adults around.
0:20:23 > 0:20:26If they don't grab as many as they can the adults will take them.
0:20:26 > 0:20:30I'm just looking at him there, he's munching on vegetables.
0:20:30 > 0:20:34I'm thinking, how much of that is he going to have to eat to fill him up?
0:20:34 > 0:20:38Because he's an adult male gorilla he's going to have
0:20:38 > 0:20:40to eat a lot more than the females.
0:20:40 > 0:20:45In the wild they probably eat something around 18 kgs worth
0:20:45 > 0:20:46of vegetation a day.
0:20:46 > 0:20:51Matt, I think my beetroot muffins have definitely been a success.
0:20:51 > 0:20:55So, as I'm still wearing my pinny and I'm in a baking mood what can
0:20:55 > 0:20:57cook up next for them?
0:20:57 > 0:21:01Maybe try banana cake and we'll have some as well, the keepers.
0:21:01 > 0:21:04Typical, I better had put the kettle on.
0:21:11 > 0:21:13Back at the De Brazza enclosure,
0:21:13 > 0:21:17Jane the vet is starting diabetic George's medical check.
0:21:17 > 0:21:20The keepers have been worried about this monkey because he has
0:21:20 > 0:21:24been looking a bit thin and they are concerned he may be ill.
0:21:25 > 0:21:27Jane checks his kidneys.
0:21:27 > 0:21:29Some people with diabetes can get kidney disease
0:21:29 > 0:21:31and it's the same with monkeys.
0:21:31 > 0:21:34- Do his kidneys feel all right? - One is a little bit big.
0:21:34 > 0:21:37We'll do some bloods.
0:21:39 > 0:21:41Next she checks his teeth.
0:21:41 > 0:21:44He doesn't have many left, as you can see.
0:21:44 > 0:21:47I have removed quite a few of his teeth already.
0:21:47 > 0:21:53We'll have a look at this canine, but the rest are in good condition.
0:21:53 > 0:21:56It may need to be extracted in the future.
0:21:56 > 0:21:58There's a little pocket at this side,
0:21:58 > 0:22:01but the rest of the tooth seems quite healthy, so we'll leave it.
0:22:01 > 0:22:06George really sort of needs all the teeth he can have and I don't think
0:22:06 > 0:22:12it will cause a problem for the next of couple of years. That's good.
0:22:12 > 0:22:15It's also an opportunity to clip George's overgrown toenails.
0:22:15 > 0:22:19You see how long the nails are
0:22:19 > 0:22:22and it can get uncomfortable and in the way and stuff.
0:22:22 > 0:22:26He's one of the only monkeys that I know of that needs his claws cut.
0:22:26 > 0:22:29They usually wear them down quite nicely.
0:22:35 > 0:22:37This one I just cut was so incredibly long
0:22:37 > 0:22:41it must get in the way when he's trying to use his feet.
0:22:41 > 0:22:45So, I think it will be easier for him to use his feet to grab food
0:22:45 > 0:22:47and walk and do whatever he wants.
0:22:47 > 0:22:51Simon was especially worried that George was looking a bit thin,
0:22:51 > 0:22:53so now they weigh him.
0:22:53 > 0:22:56About 8.1.
0:22:56 > 0:22:58It's not actually that bad a weight for him.
0:22:58 > 0:23:01- No.- Anything up to 10.
0:23:01 > 0:23:03He is an older monkey and you
0:23:03 > 0:23:08expect it to go down a bit. 10 kgs is what we've had male De Brazzas
0:23:08 > 0:23:11before but they are in their prime. He's a little bit past his prime so
0:23:11 > 0:23:138 kgs isn't bad. We'll keep an eye on him.
0:23:13 > 0:23:16We don't want it to go lower than that.
0:23:16 > 0:23:18Lastly, Jane takes blood samples
0:23:18 > 0:23:21so his blood sugar levels can be checked.
0:23:21 > 0:23:25Good boy, George.
0:23:25 > 0:23:30With all the tests done, it's time to wake George up.
0:23:30 > 0:23:33Poles in here for him to hang onto.
0:23:33 > 0:23:37Jane gives him a shot to reverse
0:23:37 > 0:23:41the anaesthetic and almost immediately George comes round.
0:23:41 > 0:23:45I just want to keep an eye on him while he comes round.
0:23:45 > 0:23:47We can with him cos he's quite a nice animal,
0:23:47 > 0:23:50he shouldn't be too aggressive.
0:23:50 > 0:23:53We don't want him falling on the floor
0:23:53 > 0:23:55so if we prop him up a bit just until he wakes up.
0:23:55 > 0:24:00It'll be a short wait for the results to come back,
0:24:00 > 0:24:01but in the meantime,
0:24:01 > 0:24:05Simon is happy that his old friend seems to be doing well.
0:24:05 > 0:24:08We've got the tests to run on the blood yet, so we don't know
0:24:08 > 0:24:10if there are any problems.
0:24:10 > 0:24:13But as far as his condition and weight I am a lot happier
0:24:13 > 0:24:16knowing what they are rather than trying to guess all the time.
0:24:16 > 0:24:20I've been round the zoos a very long time and so has he.
0:24:20 > 0:24:24He's been here for many years now. So, you get used to him being around.
0:24:24 > 0:24:29And, when the test results do come in, it's fantastic news.
0:24:29 > 0:24:33Jane has found nothing which causes concern.
0:24:33 > 0:24:37George is doing brilliantly for an old monkey. But as with all
0:24:37 > 0:24:41his animals, Simon will be keeping a close eye on his friendly primate.
0:24:56 > 0:24:59Alas, another episode of Roar is coming to a close, nearly.
0:24:59 > 0:25:02That's right cos we've got one last little job to do.
0:25:02 > 0:25:04It's important for a certain fella
0:25:04 > 0:25:06or should that be lady in the cat section.
0:25:06 > 0:25:09What's the mistake we need to correct?
0:25:09 > 0:25:11Well, obviously we are outside Tug's enclosure.
0:25:11 > 0:25:17- Tug's a male Indian desert cat. - THEY LAUGH
0:25:17 > 0:25:20We have recently found out, because we did a
0:25:20 > 0:25:25little research, and we had to catch Tug one day and we found out that Tug
0:25:25 > 0:25:28is not a male but a female.
0:25:28 > 0:25:32Wow, that's quite a big revelation. So, how did you
0:25:32 > 0:25:35make the mistake in the first place?
0:25:35 > 0:25:39Someone made a mistake in sexing the cat when we vaccinated him
0:25:39 > 0:25:41at eight weeks and 12 weeks.
0:25:41 > 0:25:44Of course we've never had to catch him/her
0:25:44 > 0:25:51since and of course we have done that and we have resexed him to her.
0:25:51 > 0:25:53It's confusing, very confusing.
0:25:53 > 0:25:55So, Tug is now a female.
0:25:55 > 0:25:59- The sign there points to a male. - That's correct.
0:25:59 > 0:26:02So, what are we going to do just put that white correction stuff
0:26:02 > 0:26:04on it and change the sign?
0:26:04 > 0:26:07- Well, we could do but from nowhere... - Oh, Jim!
0:26:07 > 0:26:09Here's one you made earlier.
0:26:09 > 0:26:12Exactly, Tug is now a female.
0:26:12 > 0:26:14Fantastic. Can we take this one off?
0:26:14 > 0:26:17- If you'd like to do the honours. - Take one side.
0:26:17 > 0:26:19- It feels like a big moment. - OK, Tug is now a lady.
0:26:19 > 0:26:23So, have you got any plans for her now that she's a female?
0:26:23 > 0:26:25That's big news, isn't it?
0:26:25 > 0:26:29- It is and what we've done we've bought in an unrelated male.- Right.
0:26:29 > 0:26:32Gumpta, who's next door, and we will pair them up
0:26:32 > 0:26:36- and hopefully we will have some babies.- Will you invite us back if
0:26:36 > 0:26:38- she gets pregnant and has little nippers?- Of course.
0:26:38 > 0:26:40Good luck with the breeding programme.
0:26:40 > 0:26:42While we say goodbye to Miss Tug why don't you stick around
0:26:42 > 0:26:45and find out what's coming up on the next episode of Roar.
0:26:48 > 0:26:52No-one likes having injections, but the team have to give
0:26:52 > 0:26:55the fierce clouded leopard cubs their first jabs.
0:26:55 > 0:26:59The new open-topped baboon enclosure has seen its fair share of drama
0:26:59 > 0:27:04including a monkey escape. What's going to happen when they put
0:27:04 > 0:27:08a black rhino in with this troublesome troop?
0:27:10 > 0:27:15Plus keeper Jim can't reach his favourite snack using his mouth,
0:27:15 > 0:27:19but we know an animal who can, find out which.
0:27:19 > 0:27:20I want my biscuit.
0:27:20 > 0:27:23That's all coming up on the next Roar.
