An Earth-bound Misfit

Cats do dream. There is scientific evidence that cat’s brain can formulate dreams during sleep. In humans, there are 5 stages of sleep where the fifth stage, REM (rapid eye movement) is where dreams occur. Similarly, cats have 2 types of sleep – REM and non-REM (deep sleep). Cats usually stay in REM sleep for about 30 percent of their sleeping time. The brain wave patterns displayed by a sleeping cat are comparable to that in humans. However, humans only spend about 20 percent of our sleep time in REM stage except for human babies that have 80 percent of their sleep in REM.
