Sweetie

Sweetie is a term of endearment derived from the Old English swete, meaning sweet in taste or pleasant in character. As a noun and name, it directly means a person who is much loved or a beloved one. For a pet, the meaning is entirely transparent — this is an animal loved deeply and completely, and the name makes no effort to hide that.

Sweetie is a name chosen by someone who looked at their pet and simply ran out of more elaborate options — in the best possible way. It's completely honest. The animal is sweet, they are loved, and the name is a daily reminder of that. It suits gentle, affectionate pets: a soft-coated dog who leans against you, a purring cat who never scratches, a rabbit who lets children hold her. Sweetie is unpretentious, warm, and genuinely expressive. Sometimes the simplest names are the most right.
