She'll be 8 weeks on Christmas.
Up until the last few days she has been walking just fine, playing, jumping, everything! Now suddenly her back feet are dragging, they're weak and she's having a hard time walking. She did not get the breast milk for more than a week in her life, her mother passed away and we've been bottle feeding her with whiskas kitten milk (She's eating hard food now). Unfortunately I believe she does have ear mites, I would be treating her for this but when we treated her for fleas she got sick and began to throw up, I asked the vet about it and they said there is nothing I can do because she is too young. She has some flea eggs on her but I try to bathe her every few days to get them off, they're mostly located around her tail. Could any of that be what is affecting her? I read that it could be feline leukemia, she has not been checked for that, but how could that be what's wrong? If you're going to say that I really need more research on it from you. I need to know what I should do, please help? I do not have a lot of money to be spending at the Vets office but if you can ballpark the diagnoses I'll take her in and ask about it, I'm willing to spend as much as I can.
Oh and by the way, she was born from an outdoor cat, she COULD be inbred but her body shows no signs of it, no extra toes or anything, could that have something to do with it? Also, adding in any other factors it could possibly be, I have 3 adult cats... Could they have injured her?
