Is it normal for cats to be sleepy in winter?

Yes, it is a normal physiological phenomenon.

Cats sleep longer than other animals to replenish energy. Sleep time every day ranges from 12 to 16, with an average of 13 to 14 hours. Some people even sleep for 20 hours, but only 30% sleep in deep sleep, and the rest sleep in non-deep sleep, which makes it easy to wake up.

In English, "cat nap" means being able to fall asleep as quickly as a cat. They often move at night, but that doesn't mean they are Nocturnal Animals.

Extended data:

Cats sometimes cock their tails, which not only means that kittens want their mothers to lick their butts, but also act coquetry. When a cat is coquetry, you will snore when you touch her head, neck, body and abdomen, which is a sign of happiness. When a cat is in a good mood, its eyes will be half-narrowed, its ears will be slightly tilted to relax, its tail will sway slightly, its feet will rub up and down gently, and it will not stare at anything special.

Eating something you like or haven't tasted for a long time may also make you snore. When a trusted person holds it in his lap and wags his tail slowly, it shows that he is completely relaxed and carefree. That's what cats mean when they spend a long time cleaning up. Some people in China think that cats can predict the weather. When they lick their front paws and wipe their heads, it means that the weather will change.
