Hi Lynn, I had a Fluffy Cat once. And He was always bringing Hair balls back. But it's a good job that they do. If they didn't, it could be very dangerous. They could get a blocked bowel, through it. You could talk to the Vet about it, but I don't think they can do anything, as it's a normal thing for a Cat to do. They get them, because they are always washing them selves. I know it's a nuisance. Because I had it for twelve Years. I'm sorry I can't be more help. Best wishes, Judith.
