Miss Hoppy has never had a problem with hairballs, and she is ten years old. WHen she is going through "the big shed" a couple times a year, I make sure to pet her and "grrom" her every day, usually we go outside and the excess fur floats away on the breeze.

She has plenty of hay available at all times, too, which helps "sweep" the digestive tract clear ... and sweep is in quotes because she'll also nibble on the straw of the broom if given a chance.
