i wouldn't be able to put these on my cat if i wanted to. They have to put my cat in a blanket to trim his nails at the vets. I would love to be able to use something like this. His claws get so long they make holes in my shirts.
I use to have to do that too, when my cat was younger.. Now he is 8 and stays still for at least the front nails, I don't bother with the back ones anymore
