How do I train this cat?
We got a new kitty, Mort, a few weeks back. I think he is about 15 weeks old right now. He can be a real sweetie, but also a little terror and I'm not sure how to best go about training him.
He has a terrible habit of coming up behind you (quietly of course) and launching himself onto your back- where he sticks by way of his claws. This is very painful, so in the moment I just want to take him off as quickly and painlessly as possible, but I'm not sure what the proper reaction to this behavior should be to change it. Once you take him off your back and set him down, he will often repeat the behavior. He will also come at your face with paws and claws swinging if you lean over- say to tie your shoe. Though he's tiny, he's also threatening, and while I think he means to just play, he's also learning to be dominant- the old cat seems to like him but is proving to be very passive.
With cats we've had in the past, we've used a squirt bottle as a training tool, but that wouldn't be an option in the above scenario where he's on my back, and in other scenarios, it is proving to not be particularly effective either. If you spray him with water when he's doing something wrong, it doesn't seem to phase him. Clearly he realizes he's wet, it just doesn't seem to bother him. He's fallen into the bathtub with me twice and while he's not thrilled about being in there, he's not very distressed either. Water doesn't seem to bother this guy. When he jumps on me, I often yell his name rather loudly (more of an automatic response than a planned one), that doesn't seem to have much effect on him either.
So how do I train this guy to not jump on my back like this? What is the proper response when he does it? I've never had a cat that did anything like this. Help!
