I recently bought this product to use on my 2 cats. One is a ragdoll and the other is a snowshoe, either way they got a lot of fur. I was using the furminator and was getting tons and tons of fur, yet every weekend I still have to vaccum my carpet to get rid of cat fur. Plus I live in Los Angeles and it's like 100 degrees right now so I thought giving my cats a trim might help them. The #1 trimmer guide is what I use because with the #2 I can't get enough fur and it ends up with an uneven cut. The clipper is amazing and I finished shaving 1 cat in 40mins and I trimmed other cat in about an hour. Easy to use and easy to clean. Be very careful using the clipper without the guides because you may end up cutting your cat's skin. Hope this helps.
