Some love it, some hate it! My beloved Pandi, she was a full short hair kitty who I started brushing around 1 years old because she shed excessively. She wasn't to happy with it at first, so I would give her treats and do it when she was seeking attention, in a cuddly mood. Slowly increased the time she was brushed and eventually I had to hide the brush from her!!!
If I pulled the brush out and fingered the bristles, she would come running from whatever, wherever she was! LOVED it!!!! Maia doesn't have the soft undercoat so I find brushing her does nothing, I don't get anything on the brush...........Deepends on the coat of the cat, if there is a lot of shedding, it definitely reduces the fur ball intake (thats why I groomed Pandi). Long hairs you have to groom them, they need help with all that fur!
