I have cats and dogs who are like family to us. They pretty much come and go as they please through the pet door in the back. The dogs have to let the cats in, though, lol, since we've got one of those sensor type doors that only opens to the sensors in their collars and the cats wouldn't leave collars on long enough to have them, lol.
Anyway, do you have any pets? If so, what do you have? Do you let them go outside or are they indoor-only?
