According to Pet Centric by Purina, the average pet cat is capable of jumping more than 5 feet high, without a running start. Depending on the cat, this can be as much as seven times the cat's height.
In addition to being athletic jumpers, cats are exceedingly fast and can run at speeds of 30 miles per hour with little effort, thanks to their extremely muscular legs. Most cats are also extremely agile and can easily maneuver around obstacles, start and stop quickly, and climb over barriers with very little trouble. Even the laziest cats are impressive athletes from a biological standpoint.
