aerial.2000, They have only been together for 2 months....close out of cage interaction is very, very, adult supervised. Neither of our cats seem to be bothered by Isaac nor appear to want to "hunt" him. Isaac was raised in an amazing pet store that highly interviewed us before we were allowed to make him ours. I say that because he had a lot of interaction with humans and other birds at his original home, but not cats, therefore we are wary of his cool, trusting, behavior around the cats....we would never trust them together without such supervision...I think so far that "Isaac" the Grey will be the dominate personality with the cats !! lol
