I don't, Cincy's mom. The cats and dogs are together constantly and do fine. But my hamster and birds are just too tempting to the other four. The cats, especially Butter, think that birds are for catching. The dogs are Retrievers and they think the same thing. They are often in the same room, but when they are, the birds are safely in their cages away from the jaws and claws of the others. Right now, all cats and dogs are outside, and the birds are out for their daily stretch in the living room.
