Why do carnivorous/predatory animals seem to sleep more than extremely intelligent animals? (lemmy.world)

For example, why do things like domestic cats and dogs seem to nap and sleep for longer than humans or elephants?

Most animals are just trying to conserve enough energy until their next meal since they haven't invented grocery stores yet. If that means they sleep between meals than that's what happens. Predators get that luxury. Prey animals sleeping all day is probably a bad idea.

Humans are also an outlier when it comes to energy conservation. Our bodies are ridiculously efficient but at the expense of not being very strong or fast. Endurance hunting is a thing humans can do. Instead of running faster than our prey we run longer than they can.
