Anyway, Jackson said that's all about a cat going bonkers because other cats outside are invading his/her territory and the indoor cat doesn't feel in control at all of the situation. One of the things he told people to do on the show is take the cat outside on a leash and walk it around the property so it can then mark it's territory and repel other cats from coming so close. There's more to it probably, but I'm sure you can get ideas from him on his site. I wish I'd known this stuff when we had those cats way back then when I was young!!!
Mine is an indoor/outdoor cat he comes and goes as he pleases or I would try that!
