Love your gallery posts, Thomas. I live in a small house with three cats and one wife, and process my film at home in changing bag/tank. Hanging the film on the shower curtain rod has worked just fine - the shower and attendant humidity knock most of the dust out of the air, and no cat hair has shown up. Of course, the cats are locked out of the bathroom while the film dries, because they find this dangling, shiny thing irresistible.
