The Zoo is back! Ah we love The Zoo - between the cute little animals being born and the dulcet tones of Tom Dunne describing it all, it's lovely viewing altogether of an evening. Tonight we meet back up with the team in Dublin zoo where there is excitement in the air at the Gorilla Rainforest area when the zookeepers discover that one of the apes may be pregnant. Elsewhere, the animal care team makes some improvements to the meerkat habitat, and vets are called into the South American House to treat a two-toed sloth. Yep, a sloth. See? It's far too cute.
