Kitten Health Please help

I found a kitten last night. I estimate him to be about 6 weeks old. He turned up at a farm where I ride horses about a week or so ago. He's so little, despite his success in surviving in the hay barn, I decided to bring him home since there are more than enough predators around. I want to get him to a vet soon but haven't yet been able (I've had him less than 24 hours).

He seems relatively healthy despite his traumatic past (We think a fox brought him to the farm yet he managed to get away. He has bite marks on his back legs.) Since I don't really know his health I have kept him quarantined from my other cats until we can fe-luk test, etc. He was eating adult cat extremely cheap cat food at the barn. I switched him to high quality dry and canned kitten food today, Chicken Soup for the Kitten Lover's Soul, to be exact.

However, prior to the food switch I noticed a slightly protruding anus. Tonight he's had soft stool in an amount that a small adult cat might have, not a 6 week old kitten (though he has eaten a lot of food since he came here). I can see the soft stool being a result of the food change as it's a new development. Any thoughts on the anus? Worms perhaps? Your help is more than welcome!

in gen grains will do that, Chicken soup for the soul is not MY idea of good cat food, but is beter then what he/she had.

What you need to do is check for fleas and keep him isolated until you see a vet, six weeks is very young to be away from mama and any litter mates. You have to foster him or give him to a recue group that can do it. I would get KMR and as far as the wounds go keep a close eye on um and bathing the kitten might not be a bad idea either.

Sorry that I'm not any help on this one, but I WOULD suggest a vet checkup a/o. For the bites as well as this, and the testing.

The bite marks are already healed over.

I'm capable of fostering the kitten. I don't think I need a rescue group.
