Cat and dog fleas are very similar in appearance. They are small. wingless insects between 1.5 to 5mm long with piercing sucking mouth parts. they are dark coloured and have very narrow oval bodies with well developed legs which allow them to be great jumpers. Their bodies are covered backward projecting spines that help them move between the hairs on the host animal. The female cat flea's head is twice as long as it is wide. both cat and dog fleas have a row of very heavy spines on the front of the head (genal comb) and the back part of the first body segment (pronotal comb)

Cat and dog flea larvae are approximately 6mm long when fully developed and look much like fly maggots/ They have 13 body segments, are a dirty white colour with backward projecting hairs on each body segment. They also have a pair of hook-like appendages on the last abdominal segment.

Cat and dog fleas go through complete metamorphosis. The female lay four to eight eggs after each blood meal. The eggs fall off the host animal and hatch in about 10 days. The larvae feed on dried blood, bits of faeces and other types of food materials. When mature they spin silken cocoons within which they pupate.

the pupal stage can last from 7 days to a year. The adult flea will often stay within the cocoon until vibrations stimulate them to emerge. The adult fleas feed on blood with their piercing sucking mouthparts, but will readily feed on humans.
