Dare you? Sometimes when a cat rolls over and shows you it’s belly it’s being friendly, and sometimes not. Beware if you reach your hand over. You can be grabbed by the front paws and kicked by the cats back legs, and don’t forget the teeth! major damage can ensue. I’m not saying disaster will happen but its worth watching for twitching tail and grabbing paws with claws out. If you don’t you can end up at the sharp end of your cat!
My cat does not like his belly rubbing or tickling even if he lies like this! Tickle his chin, that’s fine. Try and give him a belly rub, and the claws come out. He has to be extremely relaxed for me to dare to tickle him. I’ve got lots of scratches and puncture wounds in the months after we got him. Now I know him, I keep my hands away from those claws. I think it’s like fishing, he tempts you close, then – pounce, he’s got the back of your hand or a finger. Ouch!
