my sammy used to think that it was a game, he would grab the brush wrestle with it, strangle it and kick it with his back feet, not ever waiting long enough to see if it felt good or not, but he was recently neutered,and the vet tech brushed him, I guess while he was still groggy from the surgery, when I went to pick him up, the girl had him in his lap brushing him, and sammy was purring like a motor boat! Now he loves it!!!l
