Non-stop scratching. Excessive licking. Red, irritated skin. If you notice these signs in your feline friend, it's possible that fleas could be wreaking havoc on your unsuspecting cat. Unfortunately, it doesn't matter whether your cat sunbathes outside or lounges inside. With fleas, if there's a will, there's a way. 

Because fleas feed off your cat's blood, this can lead to pain, discomfort, scratching, and even conditions like anemia and tapeworm infections. While the best way to prevent your kitty from experiencing the wrath of fleas is prevention, sometimes it's too late and you need to move to the treatment step.

Some flea medications and shampoos that are made for dogs are not safe for cats, so always read the label and make sure the shampoo you choose is safe for cats, says Sara Ochoa, DVM, a veterinarian at Senior Tail Waggers with over six years of experience working at Whitehouse Veterinary Hospital in Whitehouse, Texas. When in doubt, show the shampoo to your vet before you use it, and work with your vet to develop a treatment plan to say farewell to fleas for good.

Some flea shampoos can be too harsh to use on kittens, which is why Ochoa recommends using baby shampoo. "This is very safe for small kittens," she says. Since it's made to be extra delicate for newborns, you can expect it to gently cleanse your kitten's skin and coat if she has fleas.

How to Use Flea Shampoo for Cats

If this is your first time using flea shampoo on your feline friend, you might wonder: How much shampoo do I apply? How long do I leave it on? How many times will I need to mentally prepare to bathe my cat every week?

Ochoa recommends using just a tablespoon size amount of flea shampoo and fully lathering your cat, making sure to avoid the eyes. You'll want to leave the shampoo on your cat for five minutes before fully washing it off.

"It is best to only bathe your cat once a week," Ochoa says. "If you are continuing to have flea problems, you need to try other flea control measures along with these shampoos, such as topical flea medications and treating and cleaning their environment."
