The chief defect of Henry King/ Was chewing little bits of string. –Shakespeare
Well, cats know better than to do that–most of ’em, at least.
My old cat Buster used to pick at rubber bands to make them go twang. It made for some pretty odd noises coming from the kitchen.
But when all is said and done, plain old string is a never-failing source of amusement, if you are a cat.
