thinking about how cats are solar-powered...

fun cat fact: the reason cats love sunbathing so much even at temperatures that humans cant handle is because their body temperature is about 2~ degrees (celsius) higher than ours. which may not seem like much but is actually quite a lot in terms of biological functions

this means that their metabolism is very fast (which requires A LOT of heat and energy to keep running). also their liver produces metabolic enzymes even while they sleep (unlike many other mammals who do not) this means they gotta be warm ALL the time to function ideally

of course there are exceptions and cats who evolved in northern climates have a slightly different metabolism and heat storage, but our modern domestic cats are closer related to African and middle eastern wildcats (aka where its very warm and lots of sunlight is available)
