The adults are roughly 1.5 to 4 mm in length and are laterally flattened. They are dark brown in color, are wingless, and have piercing-sucking mouthparts that aid in feeding on the host's blood.

Cat fleas are holometabolous (undergo complete metamorphosis) insects and therefore go through four life cycle stages of egg, larva, pupa, and imago (adult). Adult fleas must feed on blood before they can become capable of reproduction. [10] Flea populations are distributed with about 50% eggs, 35% larvae, 10% pupae, and 5% adults. [11]
The most infamous flea-to-human transmitted disease is the bubonic plague, which was caused by the bacterium Yersinia pestis.
The vacuum must be used around everything the animal frequents in order to pick up all the larvae and eggs. Traditional advice recommends disposing of the bag after each vacuuming.
