Cat flea eggs are less than 1MM and are oval shaped with a white color. Cat fleas themselves range from 1–2 mm long and are usually a reddish-brown color, although this can vary. Female fleas lay eggs loosely in the host’s hair (usually a cat or dog). The eggs drop off and hatch in 2-14 days into tiny, hairy, worm-like larvae. Flea larvae can be found in the kennel or cage of your animal, along baseboards, in carpets, or even on/inside furniture. Cat fleas can produce several hundred eggs in a lifetime, which for a flea can be several days or as long as a year! New adult fleas immediately seek a host and must get a blood meal in order to survive.
All types of adult fleas feed on the blood of warm blooded animals and pets. A blood meal is required for the flea to be able to start producing eggs.
Cat Flea bites are probably the most irritating aspect of dealing with these insects. They can cause red, swollen spots that are extremely itchy. A bite from a flea is actually considered a puncture wound. You’ll usually find a few bites clustered together and the bite can remain itchy up to several weeks.
