Cats do not need to leave a light on at night because the cat’s eyes are covered with a thin film. The unique eye structure allows the cat’s eyes to see things around them clearly at night, so there is no need to leave a light on the cat at night. . Even if the cat is not active at night, it still needs a very dark environment to rest, so that the cat can feel safe and rest well. If the cat turns on the light at night, its endocrine disorder will be disrupted and it will be unable to clearly distinguish between night and day, which will affect the cat's normal life.

Things to note when cats sleep:

1. Eat a full meal before going to bed. Before going to bed, be sure to give your cat a high-quality dinner, which can make your cat more comfortable and at ease most of the night.

2. Clean the cat litter before going to bed. Cats love to be clean. Owners can clean the litter box before the cat goes to bed so that the cat can lie down in it more safely.

3. No light. Lights can easily excite cats. It is best to turn off all lights and close the curtains before going to bed.
