Many of us who live with cats end up admiring their nonchalance, their somewhat cynical, life-worn attitudes and their incomparable ability to sleep so much. After all, what IS it that they do that makes them so tired all the time? Work? Ha! They have staff to do that for them.
Try to get your cat to fetch the newspaper or your slippers or even to guard your house against intruders. Hey... never mind intruders, how about guarding your house against rodents!
Cat: "What's that, a mouse? I could go over there and catch it, but I am cozy here in this puddle of sun, and if I get up, the warm spot will move and won't be so toasty anymore, and also I will have to actually walk over there, and the mouse will probably run away by then, and it's in the opposite direction of my food bowl, so I will have gotten up for nothing... (yawn) zzzzz."
So this is a never-ending question: why are cats so lethargic and how is it that they can spend so much time sleeping?
Science – as always – provides some clues. Recent research indicates that sleep helps to clear the brain of toxins, particularly those which may be responsible for Alzheimer's and other dementia-related illnesses. It would be fun to think that small "cleaner cells" are moving through the brain while we slumber, cleaning up "plaque" like over-weight park attendants with leaf blowers, but in fact that is not what is happening.
Apparently the whole brain shrinks in on itself, allowing brain fluids to wash out all the bad wastes. It's like a tidal function with the "land" receding rather than the "ocean" advancing. The brain in this receded state is apparently unable to carry on normal brain functions, and this – researchers claim – is one reason we go to sleep.
So fundamentally, sleep is good for us, good for our brains, and it may stand in the way of our developing debilitating dementia. Therefore, it is important to get enough sleep. This may seem simple enough, but once again research points out that how much shut-eye you might need is very idiosyncratic and not only varies from person-to-person but also within the same person's life, depending on what s/he is doing.
People of old used to sleep twice in a night and even referred to it as "first sleep/second sleep". They would doze off in the evening and then wake up in the middle of the night and actually DO things like visit friends or go to church.
While your friends might not appreciate you cheerily popping in with a bottle of wine at 1 AM, clearly we do need to change our whole attitude towards sleeping.
Do you wake up in the middle of the night and find it hard to go back to sleep again? Not to worry! You should go ahead and get up. Do something, like bake cookies or wash the car. When you feel tired again, you should return to bed and go back to sleep.
Do you feel guilty about taking that nap in the afternoon? Don't! That nap is helping to wash your brain clear of dangerous toxins that may give you a debilitating memory disease. In fact, you should take more naps! Why not have one in the morning AND one in the afternoon. You could call your "first sleep" in the evening a nap too, and your "second sleep" later another nap. Actually, you could call them all "cat naps".
Did you ever see a cat with Alzheimer's?
I rest my case.
