A simple question I hope! My kitten is not aggressive but occasionally when he is sitting on my knee, not being held in place and he is purring, he will stretch out, retract his claws and sink them into my hand or leg..not enough to draw blood. Also, when he is climbing down off my knee or is climbing over me to get to the other side of the settee he sometimes uses his claws, presumably to balance, which is rather painful! Can he be taught not to use his claws when he is in contact with a human rather than furniture and if so can anyone please recommend the best method for teaching him? I've tried saying ouch loudly, I've also said no and stared in his eyes and most recently I've tried moving him to a separate room for ten mins so he doesn't get any attention for a little while but it doesn't seem to have had the desired effect. Perhaps I just need to keep going with one of these techniques?
