Furminators can leave bald spots. They are basically half of a set of hair trimmer blades. Just because the cats like it doesn't mean it is good for them. That said I do use mine, and the cats love it, but I have to use multiple other brushes after to get rid of residual hair the furminator stirs up, or else I am 100% guaranteed fur balls a few hours later.
