Thanks Jax. Today was better.
The three of us dog proofed the living room and blocked off the entryways to the other rooms, and then we went to Art Street for the afternoon. We were gone for four hours and she did fine. She wasn't even panicky when we got home. She just walked up to the baby gate between the LR and kitchen and waited for us to come over by her. Nothing chewed except her bones and Kong. No potty accidents. Nothing. All she'd done was dislodge the blankets that we'd put on the couch, and that was to be expected. We even draped the couch in a plastic drop cloth first, so if she had an accident, it would just get on the blankets.
I figured if she did fine with my b/f's dogs, she ought to do pretty well with the cats and the TV turned to Animal Planet.
She did way better than any of us expected. We're in a pleasant state of shock.
