My family has an elderly cat with mouth problems. She has chronic drainage coming from her mouth, and it's become harder for her to eat.

Last year, we managed to capture her (she's wild, by the way), and the vet removed 8 badly decayed teeth from her mouth. That improved her circumstances considerably, but now she's having problems again. I've been unable to trap or catch her.

Are there any homeopathic remedies that might be appropriate for this cat? I'm searching for ideas.
