I wanted a Furminator for a long time before I actually bought one. They were in the $30ish range and that just seemed like a lot of money for a cat brush.
I do have 5 cats, though, and I had seen videos of them in action (sadly, I don’t have one of those for you here. It would have been too hard to make one and brush Mr. Baby Cat one handed.) They just looked so impressive! I’ve seen the video of someone using it on a big dog at the vet’s office and there are just piles and piles of hair!
So eventually I acquired one and when I actually remember to use it, it really is awesome. I have another comb that gets used some too, but it’s more to keep my one kitty detangled, since he develops clumpy mats in his mane. Poor Muffin! He even had to get shaved last summer. He looked ridiculous. So now I comb him pretty much every day, sometimes multiple times.
When I want to get a lot of extra hair off, though, I go straight for the Furminator. Here’s a video of what you get after just a couple minutes of furmination! And I’ve seen worse!
