I agree a male should be with a female, even if your not planning on Breeding. If you got another male there is a chance of them fighting and being territorial? And unless they are brothers/litter mates 2 males usually don't get along? Well I have both a male and female and even though I've only had her for 2 and a half weeks they are inseperable and very attached to each other they constantly play, they eat together and sleep together.
Abigail is so attached to Artie, that when they are seperated she whines/cries for him and try's to look for him.
I think you will like watching them together, they are so sweet and innocent looking.
