Any advice on hairballs?

[Randi]

You can get some dry food called Hairball Control, I think it's Hills. I haven't tried it, but it's supposed to work.

And ..... as C.C.'s mom suggest, use a brush at least a couple of times a week, cats usually love to be brushed. Do it for about 5-10 minutes every time, long firm strokes. I have a rubber brush which works very well. Fister even tries to bite it. (that means he likes it) You can also try to make it wet before using it. I'm not sure whether it's meant to be used for dogs, but you can also use it for cats.

My cat Fister never throws up hairballs, I have only once seem him throw up and that was liquid.

Good luck!
