I have knitting elbow

I've been knitting for weeks now and my shoulders and arms are finished! It's almost impossible to knit when your cats are about too, especially when they're sitting on your lap. I've tied scrap pieces of wool to the arm of the chair so that Jemima (one of my kitties) doesn't get her cat drool all over my knitted goods. I'm so worried that someone who's allergic to cats is going to buy one of my things and swell up and have an attack from all the cat hair...I found Ben (other kitty) sleeping on all my balls of wool the other morning...
