I'm so sorry to make my very first post about a problem, but I'm very worried. I received my first guinea pig as a birthday gift on March 4. My husband meant well, and I loved Penelope the moment I saw her, but unfortunately, all the research about piggles was done AFTER she came home. She was immediately given a generous living space and a few weeks later she was given a new friend. April was well received and they have been perfect housemates and best friends. Until yesterday. April has begun following Penny around incessantly, and Penny responds with a purring sound that I am certain suggests annoyance. She also seems to chase April from their "house" and they no longer eat together. I fear that April may be a male and I'm devastated, though I still haven't been able to confirm this. Could something else be wrong? I love April and Penny so much. If I do indeed have a male and female, would neutering the male solve their issues? Thank you for any help.
