We've had him just over 2 weeks. Background is that he was more or less dumped at a supermarket with his siblings (there were 8) the owner was there and claimed they were 8wks old but seemed pretty clueless.
Anyway, we took him to the vets a few days after he was rehomed with us (so, 9wks by owners dates) and the vet felt that he was very small for his age - maybe only 6wks old, but he could just be a small build of cat. So he's now anywhere between 7-10wks old.
He is very thin. His hips are extremely pronounced, and he barely eats anything. The recommend amount of wet kitten food for him to eat is 2 pouches. on a good day he might eat one. We've bought different/brands types of food and offered him a variety but he still doesn't eat enough - and favours complimentary cat food eg cooked chicken or dried food (but worry he doesn't drink enough water for that) but doesn't eat very much of those either.
He sleeps a lot and doesn't seem to want to play, very clingy to me and DH.
He doesn't scratch either, not anything at all, his claws get stuck in everything and he just hangs from his claws and waits for you to rescue him.
His fur on his back is starting to look a little greasy too.
Am I worrying about nothing? He's back at the vets Friday after next, and hates being in the cat box (honestly, goes insane) so reluctant to take him back sooner unless they can help.
