Joey's decided that the tiles on the kitchen floor are too slippery for him. Which is true - he does have a habit of doing the splits in the kitchen. So, without any training from us, he never puts more than his 2 front feet on the kitchen floor. This is an all round good thing. For us. As it means he doesn't get in the way while we're cooking.
For Joey, however, its not so good. All that food and no way to reach it.
