Sciuri are squirrels in most respects. They communicate with mental images and short, choppy, primitive sentences, often repeating words, such as "Horse-horse come! Fast-fast-fast!" They're very excitable and seem to be constantly hyper, although they're more sluggish in cold weather. They jump on EVERYTHING, and gnaw on anything wooden. They can be a trial to own, but many people enjoy them and their antics.
