This is ten strokes from the short-haired cat.
The long haired cat produced a ton of hair. Not going to buy that metal cat hair brush after all, this works terrifically, and I have these things lying around the house. Heck, I recall seeing two just lying around on the ground in town this past week. Keep your eyes peeled and you might find an excellent cat hair brush on the floor somewhere that you can pick up and take home if you need one.
