I've come to a bit of an impass with my cat ush: She's got a few bad habits that are driving me crazy, but I know ultimately that I'm the reason that she has them!! Her worst habit is running out the door every time it opens (worst because it's the most dangerous habit). I come home after work or after an evening out and as soon as I open the door she runs out as fast as she can go (she's waiting by the door), usually trips me, and just takes off. I have to chase her down every time. I do let her go outside on the porch (I'm in a 2nd story apartment) whenever she likes, so I think that she just assumes that going out any door is ok now. How do I teach her that the porch is ok but the apartment door is never ok? Do I have to just keep her in all the time?
