Charlie, like the rest of them comes and goes many times a day.
We bought this house, it had this doggy door because the owners
had a little dog. It took me a year to have a light bulb moment
and realize I could make a cat patio in the corner that this door
leads out to. The cats are safe and love to go out and come IN
many many times a day.. hey maybe this should have been in the
'routine' gallery LOL
