Well, I am glad that Carrie answered this for you, because I would have had NO idea. What she says sounds good.

I have a dog and 2 cats, and I know sometimes the dog gets frustrated because the cats are allowed on the bed, couch, etc............she justs gives us these looks like "hey! what about me???"
I think it helped a lot that we had the cats BEFORE we got the dog.

Anyway, good luck!
