A small flea among the fur of a pet.

Clue explained

A flea is a tiny, blood-feeding insect that can live on pets such as cats and dogs. Its flattened body helps it move through fur, and its powerful hind legs let it jump from host to host. Fleas can be more than an itchy nuisance: a pet may need treatment, along with its bedding and surroundings, to break the flea life cycle.
