This isn't a rabbit problem, but I was wondering if someone could help me out. I thought I would post this here because it is about one of my cavies and I know some of you also have cavies. I posted this over on the pet board too, so if you've seen this twice I apologize, but I really need some advice. One of my male cavies has come down with what I am pretty sure are either ear mites or some kind of fungus. I'm leaning more towards the ear mites though, because I have seen ear mites in rabbits and this looks similar. I'm hoping that someone with more experience with cavies can help me out. The skin inside one ear is flaky (big flakes) and the skin on the outside of that same ear is also flaky and in some places it is very crusty. Some of the hair is coming off with the crusty skin. The other ear is also flaky and has some sores. I have another male cavy in the same cage, but his ears are fine. The reason that I considered fungus was because of the crusty skin and because his ears really aren't dirty like you often see with mites. I'm still leaning towards the ear mites though because the rest of his body is fine, it is only affecting his ears. I've had cavies in the past, but have never really had to deal with this. Do you treat ear mites in cavies like you would rabbits? I was thinking of using Ivermectin topically on the ears, but I wasn't sure if it would be best to put it on the outside of the ear where the flaky skin and sores were or if it could be dropped into the ear canal. I get a little nervous using Ivermectin topically on small animals because I'm afraid of putting too much on and overdosing. My uncle suggested I use Mitex (he used it on his goats and rabbits), but I don't have too much experience with this. I know it can be dropped into the ear. Has anyone else used this on cavies before? A friend of mine (a vet tech) suggested I use some sort of ear mite product made for felines rather than Ivermectin or Mitex because of their small size. I'm not really sure what I should do and any help someone could give me would be very much appreciated. I would prefer to use something topically rather than by injection or orally. Thanks in advance.
