...she would not list herself as being a "fan" of the cat door. In theory, the door allows her to go in and out of the basement (where her food and litter are) as she pleases. So far, she just kind of bats at the door with her paw and waits for us to open the (real) door to let her upstairs.
For now, we're just leaving the flap up, because that seems to be the biggest obstacle to her going up and downstairs. Does anyone have any experience with this?
