All of a sudden, the fur on my bunny's paws started falling out, and it looks like this. It looks irritated and its calloused. When I first noticed it, I did some research and found that it could be due to the hard surface. Every day I cleaned the my room properly and put a soft carpet. But nothing changed. Her all four paws started getting worse every day. At the same time, she keeps her paw up the whole time. I was afraid something might have happened to her leg, but she’s only protecting one paw, not her whole leg. Even when laying down, she keeps it up. Could this be related to her paw, or could something else have happened? Keeping her leg in the air became even more noticeable today.
This situation really worries me, and I want to take her to the vet. But vets are very expensive here. I'm trying to save some money, i want to take her to the vet as soon as possible. During this time, is there anything I can do for her? (I’m so sorry if the translation is incorrect; I’m very anxious right now and have tried to explain my situation as best as I can in English.)
