It is well known that cats are the world’s most energy-efficient creatures.
Being fully solar-powered, cats possess highly developed light-fueled batteries that with a minimum of 12-14 hours of daily charging, can power an adult cat in total darkness at speeds (dependent on terminal velocity and wind shear) upwards of Warp 6. (kindly refer to Cat Rules 101: 3 a.m. Zoomies)

Felines are so advanced in their absorption of energy that during a full daylight charge, they often remain motionless for hours at a time (see origins of word, “catatonic”) and may emit only an occasional “meep” or “mrap” which is an indication that batteries are approaching maximum fill and may need to be “topped off” with a final dose of a piscine-based protein fuel source for optimum speed and maneuverability.
