I can barely find something cutier and more peaceful than a cat taking a nap. My cat loves sleeping in the angle formed by my knees in bed, and I enjoy it a lot.
And cats sleep more than most animals, especially as they grow older (my cat is 10 years old). So don't be surprised by the fact that the daily duration of a cat sleep varies usually from 12 to 16 hours, with an average of 14 hours. I couldn't sleep 16 hours more than 2 days in a row, I guess.
Did you know the term "cat nap" refers to the cat's ability to fall asleep lightly for a brief period? As a matter of fact, that term has entered the English lexicon since someone who nods off for a few minutes is said to be "taking a cat nap". I find that amazing.
I want to be a kitty taking a nap!!!
