About 2 1/2 weeks ago i noticed my cat had a patch of hair missing from her back left hip. It didnt look it was a hot spot or anything. It wasnt red or irritated looking, nor did she seem to even notice it. a few days later i noticed she seemed a little weird. Her left ear looked slightly different from the other. A few days after that i came home and noticed that her ear had drained, it was all crusty and such. So i figured that was why she looked kinda weird, still doesnt explain the hair loss though. So i cleaned her up and squeezed a little hydrogen peroxide in her ear. After that she seemed better, everything has been fine. Then about 2 days ago i noticed she was having trouble with her back left leg. She walks on it but keeps tipping over every couple steps. Shes fallen off the couch twice to my knowledge and landed on her side because she is not able to balance. I rubbed her hip and she didnt seem to mind, did not seem to be in pain. I am not sure what to do...i do not have enough money at the moment to bring her to a vet, my vet also does not take payment plans or else i would anyway. I am very worried about her. Any thoughts/suggestions?
