I have a hairball question?

Have you tried a grooming glove instead of a brush? http://www.wild4pets.co.uk/images/grooming_gloves....

That can often serve as a transition to grooming with a regular brush, though it may take a long transition for skittish cats.

You might also consider adding a Feliway dispenser to her environment and see if you can turn the "emotional temperature" down for her. If she's relaxed, she's more likely to be willing to be groomed.

You may also want to consider trying to mop her down with a rough terry washcloth that's been dipped in warm water and wrung out nearly dry. That's about as close as you can get easily to a cat tongue.

There are also "corner combs" that may work if she tends to scent mark doorways and the like:

Does she seem to be a social cat? If so, perhaps a second cat who would groom her would cut down on the number of hairballs. I also find with my clowder that behaviors are learned... a rescue kitten, for instance, who sees other cats being petted and groomed, will often allow grooming after watching the others over a period of time and making sure that the cat brush is not Something That Will Eat Kittens.

Whenever my 4 cats would get hairballs I would put vasline on there front paws they would lick it off and coats there stomach so they dont get hairbairs. Also, there is special cat grass that helps with stomch aches. Hope this helps good luck!:)
