I had a persian that REFUSED any grooming at all and would rip you apart if you tried! I was lucky that she never got mats. My RB Chynna LOVED being groomed and would lay for hours for you to groom him... It is funny the differance in them. Amy will also lay for hours to be brushed with the shedding tool and Giz will try to get it away from you and groom herself. Chester and Samantha are not that impressed with grooming.
