American Shorthair cats are known for their moderate energy levels, and as a result, they are generally not known for having specific times of the day when they are more active. However, all cats, regardless of breed, have innate tendencies towards certain natural rhythms, known as circadian rhythms. These rhythms can influence when a cat is most awake and active, as well as when they are most likely to sleep or rest.

For example, many cats are naturally more active at dawn and dusk, when the sun is rising or setting. This is likely due to their ancestral roots as hunters, as these are the times when they would be most likely to catch prey. Similarly, cats may become more active in the early evening when it is still light outside, but the house is quiet, providing an ideal environment for play.

It is important to note, however, that each cat is an individual, and their activity levels may vary based on their age, health, personality, and environment. Some cats may be more active during the day, while others may be more active at night. Some cats may enjoy a lot of play and activity, while others may be more relaxed and sedentary.

In order to encourage American Shorthair cats to be more active, it is important to provide them with opportunities for play and exploration. Providing toys, such as balls, toys that move, or toys that mimic prey, can help stimulate their hunting instincts and encourage physical activity. Additionally, setting up a climbing tree, scratching post, or other climbing structures can provide an outlet for their natural climbing and scratching behaviors.

Overall, while American Shorthair cats may be more active at certain times of the day, it is not a hard and fast rule and may vary based on individual cats. By providing opportunities for physical activity and play, owners can help ensure their cats are healthy and happy.
