How To Get Rid of Fleas on Cats

To get rid of fleas on cats, use a veterinarian-recommended flea treatment made specifically for cats, treat every pet in the home, and thoroughly clean your cat’s environment. Because fleas can spread quickly and linger in carpets, bedding, and furniture, consistent and thorough treatment is essential to prevent reinfestation. 

Even indoor cats can get fleas. Signs include itching, scabs, hair loss, and black specks known as flea dirt, especially around the neck and base of the tail. If you spot these signs, the following steps can help you eliminate the infestation and keep fleas from returning. 

What Are Cat Fleas?

Fleas are tiny (2–3 mm), flat-bodied brown or reddish insects. While the most common flea found on cats is Ctenocephalides felis (the cat flea), more than 2,200 different types of fleas have been identified in the environment and on pets worldwide. 

These tiny critters are wingless and survive by feeding on the blood of animals. 

Cats of all ages and breeds are susceptible to fleas. Even indoor cats are at risk of infestation, as fleas or their eggs can be brought into the home on shoes, clothing, or other pets. This means that year-round flea prevention is important for indoor cats as well as those who are allowed to spend time outdoors.  

How To Tell If Your Cat Has Fleas

Cats are often allergic to flea bites, leading to skin inflammation and itchiness. 

Although fleas can cause generalized itchiness, the base of the tail and the back of the neck are most affected. Other signs your cat might have fleas include the presence of fleas and/or flea dirt (flea feces), which looks like black pepper flakes in your cat’s fur, and skin irritation or infection, which is evident by: 

• Red bumps 

• Scabs 

• Hair loss 

• Dry, flaky, crusty skin 

How To Get Rid of Fleas on Cats

To get rid of fleas on cats, you’ll need to treat all the pets in your home, including dogs, other cats, and small mammals, such as rabbits or guinea pigs. 

When treating cat fleas, you’ll also need to treat your home, including any bedding your pets use, all carpets and rugs, plush toys, and anything else that might harbor flea eggs.  Treating your yard is also recommended. 

All flea life stages must be eradicated to prevent reinfestation, including eggs, larvae, pupae, and adult fleas. Use the following methods to get rid of fleas on cats. 

Use a Vet-Recommended Flea Treatment 

Using a vet-recommended flea preventive is the most effective treatment for eliminating fleas on cats. Many veterinary-approved products are available, including: 

• Topical flea preventives 

• Oral flea preventives 

• Flea collars 

Topical preventives are applied to the skin and kill adult fleas (some might also kill flea eggs and larvae). They are typically applied monthly, but some can last up to three months. Topical preventives are ideal for cats who don’t easily accept pills or chewable medications. They should not be applied 48 hours before or after a bath. Some topicals provide broad-spectrum coverage, treating a range of external and internal parasites like fleas, ticks, and worms. 

Oral preventives are pills or chewable tablets that kill fleas. Most are given monthly to prevent reinfestation. As with topicals, some provide broad-spectrum coverage against multiple types of parasites. 

Cat flea collars are another option to kill and repel fleas. These are worn around a cat’s neck and must fit appropriately to be effective. The medication is administered through the contact between the collar and the cat's skin. Cat flea collars tend to last several months. 

Give Your Cat a Bath 

Bathing with a medicated flea shampoo or unscented Dawn dish liquid (commonly used on young kittens) can help to get rid of fleas on cats quickly. Make sure to use a flea shampoo that is labeled for cats.   

Active ingredients in medicated cat flea shampoos are designed to kill fleas instantly but won’t prevent reinfestation later. 

The best way to prevent reinfestation is to get your cat on a prescription flea preventive like those mentioned above. 

Use a Flea Comb 

Combing your cat with a fine-toothed flea comb can help remove adult fleas. 

If you can bathe your cat, you can use a flea comb after lathering your cat’s fur to help remove fleas and flea dirt. 

If your cat is not amenable to bathing, which is common, you can use the flea comb along with one of the flea treatments described above to help eradicate the fleas. 

Treat Your Cat’s Environment 

Treating your cat’s indoor and outdoor environment is also essential. 

Any area where your cat rests or plays can harbor adult fleas, eggs, larvae, or pupae, and proper extermination is necessary. 

Thoroughly clean your home, including: 

• Hard floors 

• Carpets and rugs (including underneath furniture) 

• Furniture 

• Your bedding 

• Toys 

• Feeding locations 

• Pet bedding 

• Litter boxes 

Purging the environment of fleas requires scrupulous vacuuming, cat-safe flea sprays for the home, and possibly a professional exterminator. 

You can also spray your yard with a pet-safe flea product formulated for the outdoors or have an exterminator treat the yard for you. 

If you have a large yard or a persistent flea problem, an exterminator would be the best option to rid your yard of fleas. 

When To Call Your Vet About Cat Fleas

If your cat remains itchy or develops a skin rash, or if your efforts to cure your cat of fleas are unsuccessful, a trip to the veterinarian is recommended. 

Prescription flea products are much more effective than over-the-counter products to treat and prevent flea infestations. 

While treating your cat for fleas, keep a close eye on their appetite, behavior, and overall health. 

If they don’t seem like themselves, a veterinary visit is also recommended. 

Fleas transmit conditions such as tapeworms and bartonella, and severe infestations can lead to anemia in cats, especially in kittens and seniors. 

The following signs of anemia are considered a veterinary emergency: 

• Lethargy 

• Pale gums 

• Weakness 

• Trouble breathing 

When in doubt, schedule a visit so your veterinarian can determine the best way to rid your cat and home of fleas.
