Does anyone have any tips on getting a young cat to stop trying to run outside? My cat Charlie (18 month old neutered male) is really becoming a problem. He is, in theory, an indoor cat, has been since he was picked up on the street at 5 weeks of age. The trouble is he's increasingly sneaky about trying to get out - he'll wait until someone isn't paying close attention while going in or out, then run as fast as possible through he open door. He only does this at the back door, so it isn't as bad as it could be - he ends up in our fenced yard and we've always been able to catch him fairly quickly, despite his efforts. I still worry about him going over the fence, though, and we live near a busy street. Also, some members of my family can't seem to remember to watch for him, and I'm the one who has to drop whatever I'm doing and go get him. I would love some advice from people who have dealt with this. I don't remember any of our other cats doing this, even as kittens.
