Well, I want to wish all my appreciated readers a happy St. Patrick's Day!
At my age, I feel like I need a cat nap every day!
Forms of this metaphoric expression have been used for 200 years to describe a short period of sleep during the day. Cats sleep long periods at a time, so it may seem strange to call it by this name. Some researchers say it started in Ancient Egypt when cats were sacred and Pharaohs began to emulate the way cats sleep. But there are no records to indicate that.
