It seems that humans desperately need sleep to function properly during the day.
"Sleep" is an uncountable noun. When talking about it in general, we use no article (the zero article).
They also drink a lot of liquid, but the water in their vast oceans is entirely too salty for them.
We use "the" here because it is a specific body of water—specifically, the water in their oceans, not water in general.
Most humans love furry companions, and they firmly believe that cats secretly rule the planet!
"Cats" is a plural countable noun. When referring to cats in general, we drop the article completely.
