Eyes on the sides of the head.
Prey animals (rabbits, deer, horses, many birds, etc.) have their eyes positioned on the sides of their skulls. This gives them a very wide field of view — useful when you’re more likely to be eaten than to do the eating.
Predators tend to have forward-facing eyes for better depth perception when hunting.
The same general principle sometimes gets casually applied to certain human faces that have a wider-set or more laterally placed eye look.

Domestic cat (some more than others)
A cousin was visiting. Conversation turned to a sister’s cat whose eyes sit a bit more on the sides of its head than a typical forward-facing predator look. That led to the term “preyface,” which somehow also got applied to Sydney Sweeney and Anya Taylor-Joy.
Someone said “you should register the domain.” So it got registered. On a whim.
