We brought a stray that has been living on our deck to the vet because she was limping. The vet lanced an infected spot on her paw. We now giving her an antibiotic twice a day. Anyone have an idea how long it takes for something like that to heal? She will only eat cat treats and we have been giving her a fair amount of those. Can eating only cat treats (Party Mix) for a few days hurt her? Thanks for any suggestions.
