I actually don't believe that. Some cats are receptive to training. Some cats can be toilet trained, trained to use a leash, jump through hoops. I think the younger the cat is the more of a chance you have to train them with treats to do these things, but it depends on the personality of the cat. I didn't know in Scotland that black cats were considered lucky, I have had two all black cats so far and they make really nice pets. They love to hunt and leave their carnage on your back steps or patios, at least the two black cats I had. I had a nice fenced in garden for one of them to roam in, so he spent a lot of time outdoors, so I was lucky he didn't leave my yard, but he killed a lot of birds and moles, even sometimes small rabbits etc. Moggies are beautiful, I think the PR thing is a little silly, but it would probably make the people passing by remember the game. This article makes me miss my cats.
