Cat Flea

Natural Habitat

Found globally; typically lives on host animals (cats, dogs, humans) and in their bedding, carpets, and upholstery.

Diet & Feeding

Adults are obligate hematophages (blood-feeders); larvae feed on organic debris and 'flea dirt' (adult flea excrement containing dried blood).

Behavior Patterns

They are wingless, laterally flattened, and possess powerful hind legs for jumping. They undergo complete metamorphosis (egg, larva, pupa, adult) and can remain dormant in the pupal stage for months until sensing a host.

Risks & Benefits

Risks include causing intense itching, allergic dermatitis, and transmitting tapeworms or diseases like murine typhus. They offer no significant ecological benefits to human environments and are considered household pests.
