According to Wikipedia, a power nap, also known as a Stage 2 nap, is a short slumber of 20 minutes or less that's proven to be beneficial. Cats already seem to know this as our cat Spencer here is demonstrating in my home office.
Spencer says that these 20-minute naps increase his alertness and motor skills. Spencer does has excellent skills with my mouse, but if you received an email from Spencer yesterday the email was likely sent in error during his nap!
Spencer and his female housemate Sage were adopted at the Humane Society during a summer visit to Bend, Oregon about five years ago as adult cats.
