If you've noticed your cat has been scratching more than normal, you probably should consider that they could be hosting tiny parasites known as cat fleas.
How did your cat become infested? How do you get rid of them? Read on for the answer to those questions and more about cat fleas.
How Did My Cat Get Fleas?
One study detailed in Veterinary Parasitology found a flea that could jump 19 inches in one hop, or 160 times its body length. These jumping skills help these nonflying parasites travel easily from the ground to a new host or from host to host. Animals commonly found in your backyard — such as raccoons, mice, possums and others — more than likely carry fleas and can leave behind fleas or larvae in your yard that can easily enter your home by hitchhiking on you or a dog coming in from outdoors. Fleas can easily jump from pet to pet, no matter the species. Your cat could even simply have attracted a flea by sitting peacefully in front of their favorite screened window.

How to Identify Fleas on Your Cat
Just one flea can turn into a major infestation in a short time, as a single female can lay up to fifty eggs a day, according to the University of Kentucky. The most obvious sign of a flea infestation is a cat obsessively scratching their body. Cornell University College of Veterinary Medicine writes that fleas most frequently bite cats on the back of the neck and the top of the tail head. Since they can't reach these places with their tongues while grooming, it means they have to scratch.
If you suspect your cat has fleas, run a fine-tooth comb through their coat while they stand on a white piece of paper or a white towel. If they do have fleas, you'll more than likely dislodge tiny black specks (flea feces) and maybe even a flea or two that you'll be able to easily spot on the white background. You can see fleas with the naked eye.
What Health Problems Do Fleas Cause?
Cat fleas can be more than an irritant; sometimes they can be the cause of other serious health issues. For instance, writes Cornell, fleas can transmit tapeworms, or their bloodsucking can lead to anemia if your cat is still a lightweight kitten or the flea burden is high.
