I got an Arco (by Wahl) clipper for Christmas that was supposed to be for my horse, however I have already found it useful for shaving the extra-long butt-hairs of my two boy cats that are long-haired. They have problems with the poop clinging to the hair back there so I figured shaving it would be the way to go. I probably should have asked BEFORE I shaved them, but this was OK for me to do right?
