Looks like the Hertzko Self Cleaning Slicker Brush :> I wouldn’t recommend it for very plush longhairs, personally, though! Wasn’t able to brush through my cat with it at all when she was deep in shed as it didn’t reach far enough, and clogged up far too quickly, but ymmv ^^
I have this brush. It works well on my short and medium hair cat. Although, my short hair cat doesn’t seem to care for it. She has sensitive skin, and the hard bristles are too much for her. She prefers a soft bristle brush.
My cats love wet brushes for humans, the wet brush brand, and those detangler palm brushes. But their favorite are these combs that have double combs on the ends like two sets of combs. I find them at the dollar store. My cats are not fancy about brushes haha. Their other favorite is this vibrating brush thing from Andis which removes more hair than a furminator
