Goodness yes! I keep fabric softener sheets around. Its a tip I got from a women's magazine for flyaway hair, works great on cats -- soimply run the softener sheet down the cat's back before brushing, and viola! no static on kitty.

Just make sure to read all labels and ingredients before you use them. Some softeners might not be good to rub on the kitties... but you also only deposit such a small amount of softener. Still, better safe than sorry.
