Unfortunately I cant have animals inside the house, its not worth the hassle from my other half. Although them being nice smelling means in an emergency it might not be the awful to have them inside.
I definately would want to have a mixed sex group, or start off with a pair so could you please let me know when you have some females available as well. Could try to organsie a pick up at a show or I could nip up on the train, its worked quite well in the past, im in no hurry though as may need to build up a stock of toys and things for the cage first.
