My 2 year old female guinea pig has another issue. Zoey has some serious issues in her genitals area. I’m not so sure on how to describe it so I will inset a photo and let that do the talking. She arches her back and is in pain when she pees/poos and has been crying a lot. She also has lost some of her appetite recently and has been noticeably less active. She also had a cyst removed by a vet late July and healed very well from it. I also only discovered this yesterday night.
