I have had little Phoenix (foster kitten) since he was 3 weeks old, he is now 5 & 1/2 weeks old and is showing no interest in eating on his own, nor using the litter box. He just goes where ever in his crate. He is drinking 3/4 a bottle every time I feed him. I am mixing a/d and KMR and blending into a liquid. I have tried my 'normal' weaning tricks, putting it on their feet, putting on his face, putting in his mouth etc and he's not interested in the least bit. He had a severe respiratory and eye infection, in fact he has probably lost his right eye. But he is doing so much better. I even had to tube feed him for 4 days to get him through it.
