Cats may look lazy to us, well, they do sleep 18 hours a day…
But it is a physiological need for them. It's not laziness.
For example, the Lion sleeps 20-22 hours a day!
The problem is they sleep all day and wakes full of energy at night...!
Now, if you play with your cat just before bad time, with a fishing rod cat toy for example and give him a large meal, You have a better chance for a quiet full night sleep.
