I tested this by chance on my Persian cat who loses a lot of hair.
I had a shock when the hair quantitée removed, were everywhere ... This comb is magical but be careful not to stay too long in one place because I have a little abuse on the back and we go poil..aussi the length difference does not press too ..
But in any case I hate to be the next week to start and my cat died for me when I brush it on he wanted to leave but finally he loves brushing with furminator biensur ..
