The Most Animals That Sleep a Lot

Sleep is a universal need, and it’s not just limited to humans. Many animals in the animal kingdom also have fascinating sleep patterns. In this article, we’ll explore the animals that are known for their extended periods of slumber. From the adorable koala to the majestic lion, these creatures showcase a diverse range of sleep behaviors.

1. Koala

Koalas are famous for their leisurely lifestyle, spending up to 20 hours a day sleeping. Explore the reasons behind their extended naps and how it contributes to their survival.

The sleep pattern of this animal is incredible. Koalas live in Eucalyptus trees and consume Eucalyptus leaves while they’re awake, which isn’t often.

Koalas are so lethargic because the leaves have almost no nutritional value, leaving them with no energy.

Did you know that koalas may swallow 1 kilogram of leaves per day in the little time they are awake?

They even save leaf nibbles in pouches in their cheeks if they are hungry in the middle of the day

2. Sloth

Sloths are  animals that sleep a lot. Sloths in captivity can sleep for up to 20 hours each day, compared to 10 hours in the wild.

This animal is noted for being a lazy, plodding animal who are unconcerned about the outside environment.

Sloths spend the majority of their lives dangling from tree branches, rarely coming down to the ground.

Sloths can do almost everything from tree branches, including eating, sleeping, mating, and even giving birth


3. Squirrel

In the daytime, they are active, but they tend to sleep up to 15 hours a day at night. Squirrels are known to decorate their nests during their hibernating period, which lasts 12 to 20 hours a week.

Squirrels spend most of their time resting, despite their active and playful appearance. Sixty percent of a squirrel’s day is spent sleeping.

4. Tree Shrew

Tree shrews are animals that sleep a lot. Because the anatomy of their eyes doesn’t allow for sight during the day, tree shrews never seem to leave their nests at night.

The most surprising discovery made while researching these sleeping creatures is that their sleep patterns are more human-like than those of other rats.

It also appears that the lengthier sleep cycles allow for more precise memory development.

5. Cats

As a cat owner, you should know their sleeping habits. Curling up on the couch and dozing for most of the day isn’t uncommon for these felines, which people sometimes mistake as slackers.

This isn’t true because cats are natural predators that save their energy for hunting or, in the case of the domesticated cat, chasing birds or playing with stray threads from your couch.

6. Owl Monkey

The owl monkey is one of the animals that sleep a lot. The owl monkey has the look of an owl, with a rounded head and exceptionally substantial brown eyes.

It is a true nocturnal primate. They have an odd manner of attracting a mate: Owl monkeys cannot make a mating call since it will draw attention to where they hid.

Instead, they urinate on their hands, rub them together, and then rub their hands against trees. This practice is ‘urine washing.’

7. Python

It might seem unbelievable, but the python is one of the animals with a unique sleeping habit. The python is one of the most passive snakes, sleeping for up to 18 hours at a time.

They hunt at night as nocturnal species and then return to a haven where they may rest without being attacked by predators.

Scientists are still learning a lot about snakes’ sleep cycle, including whether or not they dream.

Snakes use a different technique of resting termed brumation, which is comparable to the hibernation cycle of some mammals, and it isn’t easy to examine their behavior because they don’t close their eyes to sleep.

8. Opossum

The opossum has to feature among the list of animals that sleep a lot.

However, the odd defense strategy of this mammal has made the word “playing possum” synonymous with appearing to be dead – although the prone opossum you see in your neighborhood is most likely deep asleep.

The misconception that opossums sleep while dangling from their tails, on the other hand, needs to be disproved.

Instead, opossums are nocturnal animals that retire to hollowed-out trunks or abandoned rodent nests after a successful hunt.

9. Armadillo

These placental animals come in over 15 different species, each with its name based on morphological traits.

The armadillo is active at night and can sleep for up to 19 hours each day. They’re antisocial and spend most of their time resting and excavating underground.

Due to their shallow natural body temperatures, they only meet up with other armadillos to mating or huddle together to keep warm.

10. Brown Bat

After a few hours of vigorous hunting after dusk, the little brown bat usually returns to its roost to resume its nap.

They’re lucky to have so much energy. To keep adequately nourished, an average tiny brown bat has to eat half of its body weight each night, while moms can eat more than their whole body weight in a single night’s hunt.

As a result, these bats do not spend the majority of their time sleeping. They also hibernate throughout the whole winter season.

11. Lion

Lions are the kings of the savannah, but even kings need their rest. Lions enjoy relaxing and lazing around. They spend up to 21 hours each day resting and sleeping. They have few sweat glands, so they wisely tend to conserve their energy by resting during the day and become more active at night when it is cooler. While lions are strong swimmers, they are not as agile in the water as some other animals, such as crocodiles. Lions can be vulnerable to attack while crossing rivers or other bodies of water.


In the vast tapestry of the animal kingdom, sleep serves as a common thread connecting species across the globe. From the lazy koala to the regal lion, each animal’s sleep habits contribute to their survival and define their place in the ecosystem
