Haspel, C., & Calhoon, R. E. (1993). Activity patterns of free-ranging cats in Brooklyn, New York. Journal of mammalogy 74(1), 1-8.
Activity patterns of free-ranging cats in Brooklyn, New York, varied with neighborhood, season, and hour of the night. Standardized partial-regression analysis identified temperature, humidity, precipitation, and hour as accounting for 32.6% of feral-cat activity. Cats in the area of private homes included free-ranging pets while those in the area of multiple dwellings were commonly feral. Regardless of neighborhood, nighttime activity was bimodal with peaks occurring at 0100 h and at sunrise. Activity levels declined throughout the autumn and increased in the spring.
