I know there have been a few posts this winter about how to deal with static-y cats. The other day I was told to put a very small amount of olive oil onto my hand and rub it in the cat's fur. Apparently it's meant to reduce static and is good for them. I put a little bit on my kittens tonight and they absolutely love it (spent a good 1/2 hour licking it off themselves...) and it does seem to help keep the static away.
ETA: And it makes their coats nice and shiny too!
