I try to furminate the cats at least once a month. They aren't long-hairs but they still need a good brushing. Thank goodness they LOVE it especially the fat one in the middle, Apolo. He will stay still and even back his stinky butt up towards me for a furminating. And, after the grooming, a nice big ass ball of fur is left over. It kind of looks like a Gremlin after you poured some water on poor Gizmo.
