I don't know about you, but my cats shed by the pound. During spring and fall, these cats shed enough fur to clothe an entire family of bald cats. I bought a pair of these grooming gloves for my old cat who liked to shed, but hated to be brushed. He hated it so much that he would actually chase me and bite me as punishment for trying to brush him.
It was a great and devious plan. I'd slip on the glove and pet him (which he liked) and he'd never know that I was actually brushing him. Muah ha ha! The problem was that a glove with rubber nubs grooms about as well as you'd expect a glove with rubber nubs to groom. That is, not at all. Why don't I ever think of these things before I buy the product!?
In the course of glove grooming this cat for ten minutes, I removed about fourteen hairs. At that rate, I'd only have to use the glove for 128 hours straight to complete the successful grooming session. So much for my plan.
If you have a cat that hates to be brushed, there may be a solution out there, but this isn't it.
