Hairball Question

I posted awhile ago about one of my cats having hairballs, so I got them some hairball treatment-the sticky kind that comes in a toothpaste like tube that you stick on their paws and the lick off. I only started giving it to them yesterday and they seemed ok with it. I don't know which one of my cats is having the hairballs, or if they both are. Is it ok to give the hairball treatment to both of my cats, if only one of them is having the hairballs?

Yep, it's perfectly safe. The gel just acts as a mild laxative and lubricant to help things through so if the cat who isn't having troubles takes it, it won't hurt her.

Thanks Jessica!
