My guinea pig Mochi keeps cleaning the same same spot, one of her back legs. I’m not sure if she is also biting it but when I was cleaning her cage her whole leg and foot was very wet from her cleaning it. I am worried that something on her skin is bothering her? Her skin on that leg doesn’t look red or irritated, and she seems fine when I touch it, she gets a bit irritated but she does that when I touch all of her legs so I don’t think it’s sensitive. This only started happening tonight and all of my other piggies are fine and none of them have ever done something like this before. Mochi and my other female have had ringworm in the past, they were both properly treasured and haven’t shown any signs since, and this doesn’t seem to be anything like ringworm so I don’t think it’s that. Can someone help shed some light into what it is? Should I be worried? Is it normal?
