I have a Maine Coon type cat, extremely good natured. He's been given a lion cut by groomers 3 times. I bought these clippers hoping they would perform well enought for the job to be done in 20 minutes, which is about how long it took the last groomer, for whom I held the cat. But these clippers were not as fast or strong. Took an hour to do 2/3s of the cat: and he was severely tried as the clippers would pull the hair. With much oiling and much soothing we got only part of the job done. If you don't want to torture an animal with this type of coat, you'll have to get the premium clippers I suppose. For animals with lighter coats, these clippers might do fine.
