While playing with my little Trixie today, I noticed she had a little wound on her rear right leg (see photos). Quick back story on her - I saved her last fall from a stray cat. She was born last spring. We had her diet all wrong for quite a while, and after posting here some months ago, we got her diet on point and have had her on calcium supplements for MBD for a little over a month now. The only thing the calcium supplements didn't seem to change is her hair loss. You can see some of her hair loss in the photos.
What should we do about this sore? I played with her for nearly an hour before realizing it was there, so she doesn't seem to be favoring it or in pain. It's a little hard to tell from the photos, but there is actually a little knot under it that I am kind of able to move around. It's very possible she snagged it on something as her cage is homemade. I'll be going over it very closely tomorrow to ensure I get anything that could have caused it.
I read that peroxide is a no no because it can eat good and bad flesh. I also read that Neosporin only works if they can't chew on it or lick it (which she will), because it can give them diarrhea. We do have a good variety of antibiotics on hand, but don't know what is and isn't safe. I currently have no way to get her exact weight, but she doesn't have any type of weight issues.
The closest vet that will see her is almost an hour away (I'm in western MD), and I'm afraid she will just try to keep her if I take her out there. I'm willing to give it a shot though if it's needed.
Thoughts?
Hopefully these images upload correctly. First time doing pictures:
