I have a five month old Persian Himalayan kitten. I brush him EVERY day for a long time. Even at only five months old, I get a whole hand full of fur brushed out every day which makes me wonder how in the heck he could possibly manufacture so MUCH fur and not be bald from all my brushing. But it also makes me wonder when I see photos of cats that are like mine as an adult with hair flowing down to the floor where you can hardly see their feet, if I stopped brushing him so vigoursly, would he have more hair? I will say that as far as I know, he has never had a hair ball so could I be brushing him too much? I just posted a photo of him yesterday at PERSI, bottom photo, that shows how much hair he has now, but this looks nothing like all these show cats I see, how can their hair be so, so long if their owners are getting a handful of fur out each day?
