If the hairball becomes large or dense enough, it may block the intestinal tract so that the cat is unable to hack or vomit it out. If this occurs, it may need to be removed by surgical means. Hairballs can potentially reach the size of a baseball.
What You Can Do:
Groom Your Cat: Since there's no reason to stop your cat from licking, brushing your cat is the most helpful way to prevent hairballs. The more fur you remove from brushing, the less the cat will have to consume. You can check out various Cat Grooming Products. You can also learn more about Grooming Your Cat.
Products: If brushing just isn't getting the job done, there are various products to help the cat easily discard the hairball. These products, which are pleasant tasting to cats, can be fed in paste form or applied to your cat's paws to allow your pet to lick it off.
