Here's why:
* Natural instincts: Like many cats, they have a natural inclination to be more active when their prey is out, which is often at night.
* Individual personality: Some American Bobtails are more energetic and playful at night, while others may prefer to sleep through the night.
* Environmental factors: Factors like the weather, lighting conditions, and the presence of other animals can also influence their activity levels.
Overall, American Bobtails are more likely to be crepuscular, meaning they are most active during twilight hours. However, their activity patterns can vary depending on individual personality and environmental conditions.
