Fleas are more than just an irritating pest for both you and your cat. These blood-sucking parasites can carry diseases between cats, infect your cat with tapeworm, cause skin infections and dermatitis, and even be the cause of anemia.
A small number of fleas on your cat can quickly escalate to a full-on infestation in the home that you may struggle to get on top of. Treatment of fleas immediately is vital, and repellents and prevention methods can help maintain flea-free homes and pets.
Many cat flea treatments and repellents contain strong chemical insecticides that effectively eradicate fleas but may cause adverse reactions for sensitive pets and owners, such as allergic reactions.
Thankfully, there is a range of flea treatments and repellents for cats that contain natural products as their active insecticide ingredients. Here are our top 10 products, all supported by positive reviews and experiences.

Buyer’s Guide: Choosing the Best Natural Flea Treatments & Repellents For Cats
What is in Natural Flea Treatments?
Many of the most common and popular flea treatments for cats available on the market contain synthetic active ingredients. All flea treatments are regulated by the EPA (environmental protection agency) and the U.S Food and Drug Administration (if the product is oral). But EPA has recently come under fire from non-profit watchdogs for “inefficient safety standards” regarding some chemicals that have been approved.
While many cats can be administered these products just fine, there are some cases of toxicity to cats from flea treatments. Responses can range from mild irritation of the skin or gastrointestinal tract to severe poisoning.
The risk for these adverse responses is higher with cats with vulnerable immune systems such as elderly, developing, and sensitive cats. As a cat owner, doing your research on what’s in the flea treatments should be a priority for you.
Synthetic products may work well for your cat and cause no issues but looking towards more natural alternatives when battling flea issues may be more suited for some cat’s health. Considering the stakes, finding a good product can be overwhelming, so read on about some key considerations when choosing a natural flea treatment and repellent for your cat.
Natural Flea-Fighting Ingredients
How to Get a Flea-Free Home
Synthetic products are popular and widespread because they are highly efficient. While natural products certainly can have just as good results, some products may be ineffective if not supported by other actions around the home.
Unfortunately, getting rid of the fleas off your cat is just one-half of the battle. While fleas need your pet’s blood to survive, they can live anywhere from 2 days to 2 weeks in the home. In addition, the incubation period for flea eggs is up to 14 days. With these facts in mind, your cat picking up more fleas weeks after successful treatment is likely.
In conjunction with treating your cat, you need to set out an unwelcome mat for fleas in the home. Here are our best tips to do so:
Our best overall recommended product is Natural Chemistry Natural Flea Spray. This product utilizes natural ingredients to treat your cat for flea naturally. It’s backed by numerous positive reviews and maybe just the product you are looking for.
For good value, we recommend Vet’s Best Plat-Based Formula. This shampoo product has great success for treating your cats for fleas both efficiently and safely, harnessing plant power to destroy and repel fleas for good, and not costing you an arm and a leg!
