Natural Habitat

Found in the digestive tracts of pets (dogs/cats) and expelled in feces or found crawling near the pet's tail/bedding.

Diet & Feeding

Absorbs nutrients directly from the host animal's intestines.

Behavior Patterns

Once shed by the host, these segments can move independently for a short period to release eggs. When dry, they resemble hard sesame seeds.

Risks & Benefits

Indicates a parasitic infection in pets. While human infection is rare, it can occur if a person (usually a child) accidentally ingests an infected flea. Risks include internal nutrient theft and digestive upset for the pet.
