I am personally not afraid of your standard house cat, but when smashing the thing between a door and the wall only makes it angry - well I'd go and get a bat. Watching a horde of cats staring intently at something off camera, which I suspect was a mouse toy or little tuft of fur on a string, is funny. One scene really jumps to mind, when the Alpha Cat is trying to scratch it's way through a pillow to get at Lindsey and Tessa. There is obviously someone crouched under the camera and using a pair of sticks with cat paws on the end. Perhaps the perfect use for this film is torturing your own cat, just turn up the surround sound and watch it run wild trying to figure out what the heck is going on.
Cats travel in packs.
