𝐂𝐚𝐮𝐠𝐡𝐭 𝐧𝐚𝐩𝐩𝐢𝐧𝐠 is to be found asleep and taken unawares. ‘Nap’ comes from the Saxon 𝙆𝙣𝙖𝙥𝙥𝙞𝙖𝙣 meaning to doze or sleep lightly or briefly, especially by day.
Such short naps are also known as ‘cat naps’ as cats frequently indulge in them, but several other animals have this habit, and can be said to have been ‘caught napping’ while doing so.
Many birds have been observed flying far out at sea at night; when these birds have to fly over vast areas of sea, where they cannot land, they stay on the wing all night.
Some birds have been observed to fly without landing for 60 and 90 hours, and they even ‘cat nap’ during flight.
P.S: I am trying to dig my memory to find all those times when I was caught napping or taken a sweet cat nap. Happy catnapping!!
