I wonder if the breeders are working on a "mini-cat" sort of like all those tiny dogs that women carry around in their special designer dog handbags. I think they'd sell. The mini-cats I mean. Well, yeah the handbags too. And little tiny cat outfits too probably. There's no limit to what some fans of mini- tiny toy-sized animals will buy.

As far as keeping them off where you don't want them... good luck. I found you have to make sure they learn their boundaries very, very young. Almost all their imprinting is done very young. After that, you'll be chasing them away from places they're sure you gave them permission to use.

Juggernaut is right about some cats reacting to the loud rattling sound like that. And CelticTiger is right about spritzing them with water. I've seen that Bitter Apple stuff that MrYum mentioned, but never tried it with my cats. I made it more fun for myself and went and bought a variety of small water pistols, good ones that don't leak. That way if they make you stop working to correct them, at least you can enjoy aiming for specific targets.
