Katie

Katie is a diminutive of Katherine or Catherine, from the Greek Aikaterine of uncertain origin — possibly connected to the Greek katharos meaning "pure," or to the goddess Hecate. It has a bright, cheerful energy that makes it feel immediately likable. Katie has been one of the most consistently popular feminine nicknames in the English-speaking world for generations, and its appeal is rooted in its simplicity: it's friendly, clean, and entirely without pretension. For pets, Katie suits a companion who is simply, cheerfully, genuinely good.

Katie rounds out the #310 spot on the pet name charts and closes this section of the rankings with exactly the kind of warm, uncomplicated appeal that made it popular in the first place. Its Greek roots through Catherine connect it to purity, and that quality — clean, fresh, honestly good — defines the companion who wears this name best. Katie is for the companion who is simply a joy: energetic without being chaotic, friendly without being overwhelming, and devoted without being clingy. The name has been loved for generations, and every generation discovers it fresh.
