I've noticed Sundae has a patch that looks fungal on her inner back leg. Can human antifungals be used for guinea pigs? I know Guinea Lynx says that Monstat 7 2% cream can be used on guinea pigs. I also have a human prescription for ringworm from when my son had it (called Lamisil) but it's a prescription med, and specifically for ringworm. I'm positive this is not ringworm, having had both humans and animals with it in the past! I'm honestly wondering about yeast, since being on antibiotics can lead to yeast infections in humans and she is on week three of antibiotics for her bladder right now. I will have to take her back for vet follow-up for her bladder and antibiotics in about two weeks anyhow, but would like to try treating her at home first if it's safe to try. Thanks in advance!
