Rusty, did you have the kit for making creepy crawlies at home? I loved mine! It was one of the best Christmas gifts I ever received. Back when cereal boxes still had little prizes I'd go for whatever brand had the jelly octopus that you could fling against the wall and watch it slowly "walk" down.
YouTube also has music tracks and videos for dogs. Some of these are meant to soothe the poor beasts while they're going to the vet. I have to say that was a failed experiment for me as my pup would not be placated by soft music. I don't have a cat. Maybe it just works better for them.
