Black rhino Kitani is due to give birth at Chester Zoo and help swell the ranks of this endangered species, but, having lost three previous calves, it is a worrying time and the keepers are concerned that things aren't going to plan. The zoo also has four rare new arrivals called tenrecs, mysterious mammals from Madagascar and, with so little known about them, the keepers try everything they can to help them breed, while red river hog Mali has given birth to twins, but tearaway dad Confetti is a threat to his own babies.
