How do internal clocks work in pets?

Pets' internal clocks, primarily governed by the suprachiasmatic nucleus (SCN) in the brain, function through a complex interplay of genetic programming and environmental cues. This master clock regulates circadian rhythms, influencing sleep-wake cycles, hormone release, and even body temperature over roughly 24-hour periods. Light is the most powerful synchronizer, with specialized retinal cells signaling directly to the SCN, but feeding times and social interactions also play significant roles in fine-tuning these internal rhythms. While all pets possess this fundamental clockwork, the precise timing and sensitivity to cues can vary between species and even individuals.
