My cavy is interacting poorly with my rabbits and it seems to primarily be based around hormones.
The shelter that I rescued my guinea pig doesn't fix their guinea pigs because they claim they are "too small".
While this makes sense for me with respect to spaying, it seems to me that because neutering is so much less invasive the procedure should be rather trivial. Am I wrong? are there other reasons, aside from removing it's ability to breed that I would not want to neuter my cavy?
