I used to shave my old cat myself. I just used the el-cheapo Wahl (I think) clippers that were about 20 bucks at Walmart at the time. I don't think they were even really "pet" clippers. It didn't look as good as a groomer job but Montego wasn't all that great at grooming himself and was a lot more comfy without all of that fur. It definitely helped with his hairball problem.
