I don't know if I'll get an answer, but hey ya never know. We have been fostering a female cat that had a litter of 6 kittens. Mom gets lots of food along with treats, so the kittens are growing! One little orange colored guy has a back end that doesn't seem quite right. He gets around without problems, but his legs tend to go out to the sides, instead of staying under his body. I've been watching him closer over this past long weekend and one time he scrambled to get away from an annoying sibling and his back legs really didn't "walk" they "pushed". Almost like flippers???? I will call the vet that is recommended by the rescue organization we're fostering for, but not until tomorrow in case they want to see him (I'm going in for nights tonight). I couldn't live with myself if it is a problem that can be fixed and I don't. My concern is, if the little guy has trouble with the litter box, it puts him into the "special needs" category and that means it will be unlikely he'll be adopted :(. Anyone have any ideas to put my mind at ease???
