Cat Flea

Natural Habitat

Found on various mammalian hosts, particularly domestic cats and dogs, and in indoor environments like carpets and bedding.

Diet & Feeding

Adults are hematophagous, feeding on the blood of mammals. Larvae feed on organic debris and adult flea feces (flea dirt).

Behavior Patterns

Flightless but capable of jumping long distances. They undergo complete metamorphosis: egg, larva, pupa, and adult. They are highly active and remain on hosts to mate and lay eggs.

Risks & Benefits

Risks include causing allergic dermatitis, transmitting tapeworms (Dipylidium caninum), and occasionally spreading bacterial diseases. They offer no ecosystem benefits in domestic settings and are considered a pest.
