New kitten got very sick last weekend. Temperature, very sleepy and diarrhoea. He ended up needing a drip to replace fluids and antibiotics. He came home with antibiotics and probiotics and started getting better at the start of the week but has been left with periodic diarrhoea. He’s quite smelly. Anyone have any experience of how to help him get better. He’s super friendly but is also climbing all over everything so it’s pretty unhygienic.
