Cat fleas are wingless insects with flattened bodies and long hind legs for jumping. They are black to reddish black in color.
What Do Fleas Eat?
The cat flea is a blood feeder and adults will remain on an animal until forced off.
What Do Fleas Do?
The flat body of the flea allows it to pass easily between an animal�s hairs and it infests both cats and dogs. Pets typically pick up fleas outdoors and carry them indoors where they rapidly reproduce. Fleas are usually most abundant in areas where the pet sleeps.
How Do Fleas Reproduce?
The female lays smooth, oval eggs on the host animal which are dry and easily slide off the animal's body to the surface below. The white eggs are virtually impossible to see against a lawn, carpet or bedding, so they rest on these surfaces until the wormlike larvae emerge. Females produce between 18 and 25 eggs every day at the rate of about one per hour. If a dog has just 10 fleas, they can produce over 1,200 eggs per week.
Interesting Facts About Fleas:
