Are calico cats nocturnal

Cats are crepuscular, meaning they are most active at dawn and dusk. There are several theories why this is. Cats have great night vision and can hunt well in low light conditions, so they aren't limited by the hours of daylight in which they can find food, unlike the challenge strictly diurnal (day-dwelling) and nocturnal (night-dwelling) animals face.

Cats are opportunistic hunters, so they will take any chance of prey at any time of day. This fact that they can hunt at anytime means they have a wider selection of prey; for example birds during day and rodents at night. This results in a higher success rate of the cat because there is less of a stress to find food in a limited time and there is less competition with other animals for the same prey.

Another reason why being crepuscular is an advantage for cats is because they can avoid predators easily; they can see well in a variety of light conditions so they are more aware of their surroundings (You try finding your way unaided in a strange place at night!), and can avoid predators that are active during the opposite time. (Day and night creatures are just getting up or are going to sleep during the dusk and dawn.) Although cats can be active at anytime, but are most active during dusk and dawn, that is why they always are tacking catnap's: to ready their body for the next round of activity!
