Does Your Cat Need a Flea Collar?

Even if fleas are not visible on your cat, she may still be infected. Any animal that spends time outside could be exposed to ticks and fleas. Cats are meticulous cleaners and will often ingest the parasites before you can even detect them. This creates new, unique dangers specific to your kitty.

Ticks are notorious carriers for Lyme disease. They can also carry tularemia and cytauxzoonosis, which can lead to feline anemia and other potentially lethal complications.

When an animal is infected with fleas, the whole household is miserable. Unfortunately, fleas are more than common nuisances. They can transmit diseases to you and your cat. Such as mycoplasma haemofelis, tapeworms, and cat scratch fever. In addition, the saliva from fleas can cause severe allergic reactions in some cats.

If you notice your cat has fleas, treat her immediately. However, you should medicate your cat prior to an infestation to avoid any exposure to these diseases. Prevention is one of the reasons why it’s important to find the best flea collar for cats; a good flea collar can save you and your furry friend a lot of trouble.

Buying the Best Flea Collar for Cats: What to Consider

There are several types of flea collars available for your cat’s protection. The most popular flea collar is chemically-based and manufactured by major brands, such as Bayer, Adams, and Hartz. However, there are several non-chemical flea collars available as well, such as amber collars, herbal collars, and electro-static collars.

There are several factors you should consider during your search for the best flea collar for cats, especially when you’re considering a chemical-based collar. Take note of the flea collar's dispersal of active ingredients, the fit, overall protection, and weight and age requirements.

Chemical collars kill ticks and fleas by releasing pesticides. Dispersal can happen two ways. The first, and least effective, method releases a localized toxin that only kills parasites in the vicinity. This method can be more dangerous for your cat and raise the likelihood of a toxic reaction. The second method releases toxins that infiltrate your cat’s skin to provide wholesome protection, similar to topical treatments.

Since you are exposing your cat to potentially harmful chemicals, it’s important to purchase a high-quality flea collar from a reputable brand. When in doubt about a product, ask your veterinarian for her experiences.

Age and Weight

Age and weight also play a significant part in your search for the best flea collar for cats. Manufacturers will post specific guidelines to ensure the safety of your cat. These guidelines may vary, but in general, cats must be over 8 weeks of age and weigh over 5lbs to use a flea collar. Failing to adhere to these restrictions increases the chances of injury or even death.

​Ensure that the flea collar will fit your cat. The collar should fit snugly around your cat’s neck but also be loose enough to allow your cat to escape if the collar is snagged. A good rule of thumb is to allow one to two fingers inside the collar. Some flea collars offer a quick release option, allowing your cat to easily break away from the collar.

​Finally, research the specifics of the flea collar’s protection. Killing the current infestation is only the first step to a parasite-free cat. The best flea collar for cats kills ticks and fleas at any life-stage.

Benefits of Using a Flea Collar

There are several flea and tick preventatives on the market, such as oral tablets, topical treatments, and flea collars. In previous years, flea collars received a bad rap for adverse reactions to toxins and a lack of efficacy. However, recent advances in flea collar technology have led to a resurgence of popularity. Flea collars now last longer than many topical treatments, can be just as effective, and do not cause unsightly, oily skin. In addition, flea collars can be less expensive than topical and oral treatments and are easy to apply.

Natural flea collars come with additional benefits. Herbal collars can release a pleasant aroma that can calm your pet and protect them from parasite infestations.

Controversy of Chemical-based Flea Collars

Even the best flea collar for cats comes with risks. Like any chemically-treated product, you should take care when applying. If a cat has a reaction to a flea collar, he will usually show it within the first couple days. Take note of any warning signs, such as lethargy, lack of appetite, clumsy movements, and behavior changes. Closely monitor the area around your cat’s neck. Look for signs of an allergic reaction, such as redness and hair loss. If your cat develops any of these symptoms, remove the collar immediately and speak to your veterinarian.

You may want to investigate natural flea collar alternatives if your cat has an adverse reaction to a chemical-based collar. However, keep in mind that natural flea collars come with associated risks as well. Some pets may have allergic reactions to the oils and herbs impregnated in the collars.

The 5 Best Flea Collar for Cats

Bayer Seresto Flea and Tick Collar

If your primary concern is longevity and reliability, consider the Seresto Flea and Tick Collar. Bayer is a well-established manufacturer that specializes in the production of several flea and tick preventatives, such as K9 Advantix and Advantage II.

Seresto works similarly to a topical treatment. It releases imidacloprid and flumerthrin gradually, which spreads across your cat’s skin. Imidacloprid and flumerthrin are highly effective ingredients, known to kill fleas within 24 hours and larvae for up to 8 months (Parasites and Vectors).

Seresto also lasts much longer than competing flea collar brands, allowing your cat to remain protected for an additional two months, depending on water exposure. As time progresses, Seresto gradually replenishes the chemicals, reducing the chance of negative reactions, and allowing complete coverage for eight months.

The Pet Gallo Flea and Tick Collar can be a budget-friendly alternative to Seresto. Like Seresto, this flea collar releases chemicals across the cat’s skin. Pet Gallo also claims to kill the fleas in every life-cycle, protecting your cat from second generation infestations. The actual design of the collar shares many features with the Seresto collar, such as an improved scent, water-resistance, and a breakaway design. The breakaway design can save you and your cat from unnecessary heartache. If your cat likes to roam through the woods, this feature can help him escape if his collar gets caught.

The downside to this product is its lack of thorough customer support and established brand standing. Although most cats are effectively treated against fleas and ticks, Pet Gallo does not have nearly the rapport that a large manufacturer has.

Tetrachlorvinphos, the active ingredient in the Pet Gallo collar, can be harmful to small children and pregnant women. Pet Gallo collars only have a small amount of this chemical, but if anyone in your household is at risk, consider an alternative.

If brand standing and tetrachlorvinphos exposure aren't a concern, consider this collar. The Pet Gallo Flea and Tick Collar comes with a promising full money-back guarantee and should be an option for any budget-minded buyer looking for the best flea collar for cats.

Baltic Secret’s Baltic Amber Collar

This collar dual serves as an aromatic protectant and an electrostatic protectant. As the raw amber pieces rub against your cat’s fur, an electro-static charge is generated, deterring insects. In addition, the friction from the amber also gives off a resinous aroma that further discourages infestations.

The manufacturer recommends changing the beads twice a year or when they become polished. As a non-chemical alternative, this product greatly minimizes potential allergic reactions for your cat and eliminates the risk of toxic reactions. However, some sensitive cats may develop an allergic reaction to the amber pieces. Be sure to monitor your cat for signs of an allergic reaction.
