> Most often at 5 am, for whatever reason.

Cats are crepuscular animals. They are "programed" do start at 5 AM, hunt, and go back to sleep until afternoon. Living in homes tweaked them a little, but the 5 AM thing is still strong in a lot of them (mine included).

Is this because I laughed when our family dog fell down the stairs when I was six years old?

> crepuscular

So not specifically at 5AM, but around twilight. In my area, and for my cats, that changes a lot between summer and winter.

Same for my chickens, which is why "automatic chicken doors" are difficult/impossible around here: It'd need to calculate sunset and sundown, and then also consider clouds and trees: in winter the sun sets around 16:30, but the low angle makes sunlight more blocked by clouds, particles and trees and such. My chickens often decide its bedtime before 16:00 already.
