I am not a cat either, but I do live 52.5 degrees North and quite often visit 57.5 degrees North. Daylight saving is not arbitrary for daylight liking non-cats
But daylight saving occurs during the time when you already have more daylight than the vast majority of habitable landmass does. You aren't "saving" daylight at all during the daylight poor months when you're inside at work during the entire daylight period.
