Beanie

Beanie derives from bean — from Old English bean — with the diminutive suffix -ie added for affection. A beanie is also a small, close-fitting knitted cap, suggesting something compact, cozy, and soft. As a pet name it evokes smallness, warmth, and a certain round, compact perfection.

Beanie is the name for the small, perfectly formed pet — the one who fits in a bag, curls into a perfect circle when sleeping, and could be mistaken for an unusually soft hat. It's an endlessly affectionate name that suits tiny dogs and cats with compact, round silhouettes. Beanie has that double-e diminutive energy that makes small animals sound even more delightful. It's also completely gender-neutral in practice, which makes it broadly useful. Any pet named Beanie has been loved into their name by someone paying close attention.
