We have a dog, 2 cats, 11 fish, 1 corn snake, and soon to get 3 crested geckos. We used to have 2 ferrets. They were great. Had to sell them though due to the fact that we couldn't let them out as much with the cats and the male bit me and my child. But we still keep in contact with the people who bought them. It was a 14 year old girl who knew exactly what was needed. So I truly believe that any and all pets can be together in one room. That's just my two cents worth though.
I don't suffer from insanity, I enjoy every minute of it.
