The cat flea, scientifically known as *Ctenocephalides felis*, is a small, wingless insect that primarily infests cats and dogs. These fleas are about 1-3 mm long and are known for their ability to jump long distances. They feed on the blood of their hosts, which can lead to discomfort and health issues for pets. Fleas reproduce quickly, with a female laying up to 50 eggs per day. Their life cycle includes stages as eggs, larvae, pupae, and adults, making them challenging to control. Effective treatments often involve both topical and environmental measures to eliminate fleas and prevent future infestations.
