Buttercup

Buttercup is an English nature name taken from the bright yellow wildflower (genus Ranunculus), whose name combines 'butter' and 'cup' in reference to the flower's glossy, cup-shaped petals. The flower has been associated with sunshine, meadows, and simple joy for centuries. As a pet name, it carries a golden, cheerful quality that suits a sweet, sunny-natured companion perfectly.

Buttercup is impossible to say without smiling — it's that kind of name. Warm, golden, and a little bit old-fashioned in the most charming possible way, it suits a pet who brings uncomplicated happiness into everyday life. It works especially well for pets with yellow, cream, or golden coats, where the floral connection feels even more natural. Buttercup is playful enough for a bouncy puppy and gentle enough for a quiet, affectionate cat who just wants to sit in a sunny spot.
