I put those rubber cat claw covers on my cats claws to stop her from damaging my doors, furniture, her sister etc. It's worked very well, she was used to them by the end of the day. Now it's three weeks later and it's dawned on me...you can't shorten them as they are growing out because you'd have exposed claws again and what about when it's time to put on new ones, how do you get the old ones off? Any advice?
