Why do cats sleep so much?
Cats can sleep to regulate body temperature, as well as for pleasure. Cats sleep an average of 15 hours a day. Some of them stretch for 20 hours, especially older cats and kittens.
Cats have evolved to sleep longer throughout the day. Wild cats need to sleep to conserve their energy to hunt, chase and kill their next food. Although domestic cats do not need to hunt, due to the heredity the instinct make them to sleep and prepare for the hunt.
Do Cats really sleep for the entire hours?
Cats do sleep deeply but not always. Like people, cats are often just snoozing. Light sleeping makes up about 3/4 of our cat's sleep time, with just 1/4 of their sleep time being devoted to deep sleep.
When cats are snoozing lightly, they get the rest they require but they are still alert. When cat is snoozing or napping you may notice that their eyes are slightly open or their ears still twitch and turn towards the noise. So, they do not sleep deeply the entire hours.
Why do cats more active at night?
This is because over millions of years, cats have evolved into predators in low light, and their eyesight is particularly suited to late-night activity.
- Kittens will likely sleep most of the day
- Adolescent cats may have irregular sleep patterns with intense playful periods
- Adult cats sleep an average of 12 - 20 hours each day
- Senior cats sleep more than younger cats because they have less energy and less movement
