I recently lost my 11 year old piggie and it was very sad because I'd had her for a very long time and I adopted her. I had another guinea pig to keep my old one company and she got very lonely when the old one dies. My friends recently brought me a new piggie called popcorn she's 12 weeks old and I'm very attached because she's extremely cute. Unfortuantley she seems to have a patch on her neck/right shoulder and it seems a bit scabby, I don't want to make a fuss out of nothing and go see a vet unless it's vital. When my friends gave her to me she had a scab under her nose so I think she may have been in some fights at the pet store , could this just be a scar, could it be mites, should I get my other piggy treated aswell? please help I'm new on the site and I don't really know what to do.
