> Cat’s eye movements were coded using actions defined in CatFACS, an anatomically based system designed to objectively measure facial actions based on their underlying muscle movements.

Whoever named this system was clearly aware of the meme. I'd like to remain subscribed to CatFACS, please!

Haha, in case you're not aware, FACS is an well established system for categorizing human face movements https://en.wikipedia.org/wiki/Facial_Action_Coding_System

Did you know, cats are believed to be the only mammals that don't taste sweetness! To unsubscribe at any time, reply STOP to this message.

I have heard (and perhaps misremembered) that the only taste receptor remaining to whales detects saltiness, which seems a bizarre outcome given that their mouths are constantly filled with brine.

Maybe because it is useful for the whale to know if it suddenly entered freshwater? Idk
