Cats are Nocturnal
Cats are not nocturnal, but crepuscular. This means that they are most active at dawn and dusk. They are not as active during the day or night, but they will still sleep for significant portions of the day.
There are a few reasons why cats are crepuscular. First, their vision is better in low light than humans. This allows them to see better at dawn and dusk, when there is less light. Second, their hearing is very good, and they can hear prey animals moving around at dawn and dusk. Third, their sense of smell is also very good, and they can smell prey animals at a distance.
Cats are predators, and they hunt at dawn and dusk when their prey is most active. They are also more likely to see and hear their prey at these times. This is why cats are crepuscular.
If you have a cat, you may notice that they are more active at dawn and dusk. This is perfectly normal, and it is just their natural behavior. You can help your cat to stay active at these times by providing them with toys and activities that they can enjoy. You can also make sure that they have plenty of food and water available.
