Koala
Sleeps for: 18-22 hours a day
Snooze Stats: You know how you feel like passing out after eating a juicy burger and a side of chili fries? That's how a koala feels after nomming on eucalyptus leaves. The fiber-heavy diet requires a lot of energy. In order to digest it all, koalas spend 75 percent of their day dozing in the trees.
Sloth
Sleeps for: 20 hours a day
Snooze Stats: Sloths are arguably the laziest animals in the animal kingdom. But who can blame them? If you moved as slowly as one of these guys, you'd be just as lethargic. The leisurely animals spend most of their day hanging out in the treetops of their rainforest homes. They do everything in these trees, from sleeping to giving birth. Why move when you can do everything in one place?
Giant Panda
Sleeps for: 10 hours a day
Snooze Stats: Pandas tend to do two things with their day: 1. Sleep; 2. Forage. After a long day of finding and feasting on bamboo, a giant panda loves to climb up into its favorite tree and sleep.
Lemur
Sleeps for: 16 hours a day
Snooze Stats: During the day, lemurs are very independent creatures, going about their day on their own. However, at night, they often sleep in groups. They like to clump together. Talk about a cuddle sesh!
Lion
Sleeps for: 18-20 hours (sometimes 24 hours a day!)
Snooze Stats: Sometimes, the weather in Africa can be scorching hot, and all lions can do is sleep through it. It's for the best, however, because when they are awake, lions are extremely active, with all of their hunting and fighting.
Armadillo
Sleeps for: 18-19 hours a day
Snooze Stats: Armadillos are most active in the evenings, so they spend most of their day sleeping. But scientists still haven't figured out why these animals are so sleepy. One theory is because they're such stationary animals.
Cat
Sleeps for: 18 hours a day
Snooze Stats: If you have a house cat, you know that they spend most of their day napping. Scientists believe that this is a trait from their ancestors, who had to conserve energy for hunting.
Spiny Anteater
Sleeps for: 12 hours a day
Snooze Stats: Although spiny anteaters aren't as lazy as sloths, they are very slow-moving animals. Spiny anteaters, also known as echidnas, are generally solitary creatures and avoid the heat of the sun during the day. Perhaps that's why they sleep so much.
Squirrel
Sleeps for: 14 hours a day
Snooze Stats: Squirrels love to sleep because their diet is rich in carbohydrates, protein and fat. These furry creatures usually sleep in nests made of twigs and leaves filled with fur, feathers or other soft material they collect from the ground.
Tiger
Sleeps For: 18 – 20 hours
Snooze Stats: Tigers like to sleep on a full stomach. After they make a kill and chow down, they take a nap near their food. They do this to protect their dinner from any other hunting animal in the area. Once they're done snoozing, tigers wake up, hunt down another meal and do it all over again.
Owl Monkey
Sleeps for: 17 hours a day
Snooze Stats: Owl monkeys are a truly nocturnal animal. After sleeping 17 hours during the day, they are mostly active at night.
Brown Bat
Sleeps for: 20 hours a day
Snooze Stats: Can you imagine only being awake for four hours a day? Brown bats also hibernate half the year because of the scarcity of food.
Hamster
Sleeps for: 14 hours a day
Snooze Stats: The average hamster will sleep throughout the day. For most new hamster owners, this is alarming, but these small and furry critters actually require more sleep than most other pets and humans.
Pig
Sleeps for: 12-14 hours a day
Snooze Stats: When pigs sleep, they like to snuggle close to one another. They love it when their snouts touch. Just like humans, pigs dream when they are sleeping.
Treeshrew
Sleeps for: 15 hours
Snooze Stats: Treeshrews spend the daylight hours looking for food and shelter. They live in rainforests and are sometimes arboreal. Most of the time, treeshrews are on the ground but when it's dry and empty on the ground, they take to the trees for shelter!
Hippo
Sleep for: 16-20 hours a day
Snooze Stats: Hippos that stay together, sleep together. They tend to take naps in groups of up to 30. Although they can sleep on land, hippos are also able to sleep underwater. During their underwater slumber, they must rise to the surface for air, but are still asleep during this activity we humans might refer to as "sleep snorkeling."
Opossum
Sleeps for: 18-20 hours a day
Snooze Stats: Opossums are very slow-moving creatures, and will adapt to any environment where food, water and shelter exist. They're as easygoing as it gets. This also applies to their slumber, as long as their area is dark and secluded. Opossums are nocturnal.
Python
Sleeps for: 18 hours
Snooze Stats: These snakes can be quite lazy. They spend most days snoozing to save up energy for shedding. It takes up to a week's worth of sleep to prepare pythons to shed their skin. They also have trouble with their food, only eating once a week and expending tremendous energy in order to digest it all.
Duck-Billed Platypus
Sleeps for: 14 hours
Snooze Stats: The strange-looking animal gets a lot of sleep, but what's most important is that they get a lot of GOOD sleep. A study found that platypuses get about eight hours of REM sleep every day. REM sleep is the deepest sleep possible when it comes to sleep cycles. The platypuses spend their days snoozing away so that they can be up at night and looking for food.
Pocket Mouse
Sleeps for: 20 hours a day
Snooze Stats: These little mice spend their entire day getting some shut-eye. Their sleep is known as "torpor." It's a shorter version of hibernation, and pocket mice drop into it every day to conserve energy. They spend all summer gathering seeds for the winter months, and they need lots of rest in order to prepare.
