furball

Synonym discussion
Sense: noun/2
Both 'furball' and 'hairball' describe the mass of fur that a cat or other grooming animal brings up. 'Hairball' is the standard, more formal term used by veterinarians and in pet-care instructions; 'furball' is informal and slightly playful, though it is the preferred word in many everyday conversations. 'Fur' alone refers to the soft hair covering an animal's body, not to the clump that comes back up. For example, a vet might say 'Your cat has a hairball problem', while a pet owner might say 'The cat left a furball on the rug again'. If you are writing a formal care guide, use 'hairball'; in casual speech or writing about pets, either word works.

Etymology
A compound of 'fur' (the soft hair covering an animal) and 'ball' (a round object), first recorded in the early 20th century. The meaning 'a lump of swallowed fur' (sense 2) appeared first, describing what a cat coughs up. The affectionate sense (sense 1) for a cute furry animal developed later by playful analogy, as if the animal itself were a living ball of fur.
