introducing

Question
We have a male glider who is 3 1/2 yrs old who recently lost his female partner. He previously had been with other gliders in his past while with a different owner and never attempted to breed and still hasn't. He is not neutered though.  We have a friend wanting to give us her 2 gliders so he isn't alone, one is a female and the other is a male, the male is neutered ,The girl is 1 and the boy is 2 1/2 yrs old.  We have read up on how to introduce them and all but do we need to be concerned about the 2 males fighting or should they be ok since on is neutered????

Answer
It is typically suggested to neuter all males to prevent any fighting. It's possible that your current male is sterile, but that doesn't mean that he won't have the testosterone. Males are also more prone to fight when there is a female involved. It's my advice to have your male neutered, to be on the safe side.
