I've been a cat owner for the grand total of 3 weeks. My poor 5mo kitten has been suffering from d&v for a week, hasn't been eating and has lost a lot of weight. He's skin and bones :( He's been to the vet's 3 times for treatment and IV fluids and there's nothing obstructing his guts or obvious parasite or infection. We've resorted to syringe-feeding him just to get some nutrition in. I'm reading up as much as I can on what to do but I feel completely unqualified for this situation. Any advice?
