Thanks, Freedom. That's what I figured, too, but it's been 5 weeks! LOL I live in a multi-level home. The main floor has the kitchen, dining, and living room. The upper level is off limits to the dog and has 3 bedrooms (including mine) and 2 bathrooms. This is where the kitties have "their space" and can roam without haing to worry about the dog getting them. Trouble is though, if they hear him down on the main floor, they won't come out of my room at all! They have everything they NEED up there so I suppose they figure they don't have to get to know the dog but I feel like they are living in solitary confinement now.
They only come down to the main floor if they know the dog is outside or in my son's room down in the lower level.

Should I ask my vet about putting them on an anti anxiety med until the can learn to chill out ad get to know him better?
