Our Kai was born into a madhouse of 10 cats, dogs, goats, chickens... all of whom got fed as and when the owner could feed them. So, he went hungry a lot. That showed, when my daughter got him, she had to restrain him gently and retrain him to let Kit eat and he could have what was left (not much) rather than shove Kit out of the way and eat it all. So, one very serious cat. He had never been taught to play, never given any toys. My daughter says one night at the flat she rolled a ball at him. He batted it away and turned his head away from her and refused to look at her. His idea of 'play' is to engage Kit in mad chases around the house, start a fight (he should have been named Scrapper) or do this fighting round doors, curtains, etc. The mouse game we bought, which Kit loves and plays with for ages, is ignored, as are all the balls with bells in (and with no bells) tassels, straws (Kit has been known to play for half an hour non stop with a straw) rolled up paper balls, etc. He will attack and bite the edge of the rug, but that's a passing fad, then he goes and lays down very quickly. House cats need exercise and stimulation but - all this passes Kai by. He sits sleepy eyed and watches Kit playing madly before shutting his eyes as if it's too much for him. Neither of them like the wind up clockwork mouse, they ignore it, they do like catnip balls and toss them around sometimes, but all else - not for our Kai. Looking for ideas, please, on how to stimulate his interest, stop him cat napping all the time, and keep his muscles in good shape.
