Hi, I have, as Rocky pointed out, a bit of a menagerie!
I have two cats that for the most part live peacefully along side Dave, my Blue fronted Ammie [and my five dogs]. The rule is to make sure that at no time they are left alone together, even when you think they get along famously I would imagine that you like me would never forgive yourself if one of them were to hurt the other. I say it like that as in my house it would most probably be the cat that came off worse!
I'd say go for it my lot all live pretty much trouble free and it it a mad thing to see when they go nose to nose on the back of the sofa!
