Dublin Zoo is home to a vast array of animals, including mammals, birds, reptiles and insects – each one different to the next. With so many animals to look after, the question is what do you feed them and where does the food come from? This week, Gerry takes a trip to Kildare to find out. At the red ruffed lemur habitat, three beautiful new pups are born. Ciaran and Laura give them a quick health check before they go out onto their island for the first time. And at the African Plains, a zebra with a serious toothache gets a visit from the veterinary team.
