I've tried to let them come into my place (putting my cats in the bathroom) by holding the door open just to see what they'd do. They SOOOO look like they'd like to come in and stay a while, but never do. They get as far as the door and then step back. I guess that's what happens when you've been living your whole life outside. I have absolutely NO respect for that dentist. I wouldn't go to him if all my teeth were rotted and falling out!!!
