What is the Best Cat Flea Collar?

What You Need to Know About Flea Collars

In most cases, your flea collar will deliver a chemical treatment to your pet. With that in mind, it’s essential that you know the facts about these treatments so that you can make the best choice for your pet’s health. Here’s what you’ll need to know:

What Are Fleas?

Fleas are a tiny parasite that preys on all sorts of different mammals, from humans to cats and dogs. These ugly little pests are designed to optimize their ability to feed, and their food source is blood. They’re tiny, but bites from fleas can be exceptionally itchy, and cause a range of skin problems for your pet. It’s essential to get rid of them as quickly as possible.

Flea Treatments

When it comes to treating fleas, there are several different options, including topicals, shampoos, dips, oral drugs, and collars. When it comes to any treatment, it’s vital that you’re choosing a treatment that’s made especially for your pet and their weight and age. Many flea treatments designed for dogs can be harmful to cats.

Topical Treatments

These treatments are applied in the form of a gel or oil once a month on your pet’s back. While this method is easy to use, it does involve introducing potentially harsh chemicals to your pet, and many cat owners opt for other methods before resorting to topicals.

Shampoos and Dips

Another popular option for flea treatment is grooming products such as special shampoos, or a dip or rinse with a special product that repels and kills fleas. Unless you’re one of the rare few cat owners that have a cat that likes taking a bath, these kinds of methods may be more trouble than you’ve bargained for.

Oral Treatments

With oral treatments, a pill or capsule is given to your cat with their food, or with a treat. These treatments may be difficult to administer your pet, and they don’t provide a long-term solution when compared to topicals or a flea collar. While they may be a good option for your cat, there could still be better options available.

Flea Collars

Flea collars are a wearable collar that’s been treated with a solution that repels or kills fleas. They offer protection against fleas for many months, making them a good option for owner’s who may forget to reapply a topical treatment on a monthly basis. Most collars kill and prevent fleas by using chemicals, which can be a safe way to treat and protect against fleas when appropriately applied.

What to Know Before Buying a Flea Collar

Since you’ll likely be dealing with a chemical treatment, it’s crucial that the product you’re purchasing is not only effective, but also safe for your pet to use.

Size is Everything

It’s critically important that the collar you’re choosing is sized correctly for your pet. Not only is this important for ensuring a secure, comfortable fit, but different size collars have different concentrations of their active ingredients.

A collar that’s too small won’t deliver a sufficient amount of medication for your cat, and a collar is too big may provide too much, which can result in irritation and side effects.


Flea collars are designed to protect your cat against fleas for a reasonably long period, with some collars lasting as long as eight months. A collar with a longer lifespan may provide more value compared to a collar with a shorter lifespan. Long life collars are also an excellent option for forgetful pet parents who may forget to reapply a flea treatment on a monthly or quarterly basis.

Types of Flea Collars

When it comes to flea collars, there are two different types. Solid flea collars and liquid flea collars.

Solid flea collars are made with a solid insecticide which gets combined with the material the collar is made out of. As the collar rubs against your cat’s skin, it releases the insecticide onto your cat’s skin, which either kills or repels adult fleas. Some collars combine a flea repellent with an insecticide which both repels and kills fleas.

Liquid flea collars feature a liquid flea repellent which releases from the collar as a gas. While these collars are an efficient way to prevent fleas, they’re less effective at killing fleas that may already be on your cat.

The Best Flea Collars For 2022

For many cat parents, a flea collar is the most effective and easiest to use treatment option for fleas. If you decide to go with a flea collar, here are the top options on the market.

Bayer Seresto Flea and Tick Collar Check Price

The Bayer Seresto collar is arguably the most popular and most effective flea collar on the market. Not only does this collar repel fleas, but it also repels against ticks as well, which makes this collar an all in one solution for treating common parasites.

Given how effective it is, it’s no wonder that veterinary professionals often recommend the Seresto collars. These collars combine two active ingredients. Imidacloprid works to control flea infestations, while flumethrin repels and kills ticks. These two ingredients are integrated into the collar’s material, and they protect your cat for eight months.

The Seresto collar starts working as soon as you put it on, and will kill any existing fleas on your cat within 24 hours. Pet parents are sure to appreciate that the collar is odorless, non-greasy and easy to apply.

  • Long lasting
  • Most effective collar on the market
  • Includes safety reflectors
  • Safe for any cat older than ten weeks

Hartz Ultraguard Flea and Tick Collar Check Price

The Ultraguard flea and tick collar from Hartz offers an economical option that may be an effective solution for your cat’s flea problems.

The Ultraguard collar is treated with chemical flea and tick repellents that work to kill adult fleas and halt the life cycle of fleas who have yet to hatch that may be living on your cat.

This collar has a unique breakaway design that will come off if your cat becomes stuck on anything, so it’s designed with your cat’s safety in mind.

Ultraguard provides seven months of treatment for your cat, and considering how affordable this collar is, treatment breaks down to a dollar and change each month.

Unlike the Seresto flea collar, the active ingredients form as a white substance on the surface of the collar so that this collar can feel a bit greasy. As with any chemical product, you’ll want to wash your hands after handling the collar thoroughly.

While this collar is safe for most cats, some cats may experience redness, irritation and hair loss around the collar.

  • Affordable
  • Long lasting
  • Breakaway design for safety
  • Water resistant


  • Greasy to the touch
  • May cause more irritation than other collars

Bio Spot Active Care Flea and Tick Collar Check Price

The Active Care collar from Bio Spot provides seven months of flea prevention, and six months of tick prevention for your cat, which is similar to the Hartz Ultraguard collar above. Just like the Ultraguard collar, this option also features a breakaway design that allows the collar to come off if your cat gets caught on something.

The universal sizing of this collar allows it to fit cats large and small, and it’s safe for any cat older than 12 weeks old.

While the Bio Spot collar is effective for many cats, some cat owners have complained that this collar was ineffective at protecting against and killing fleas. Considering it’s low price, it still may be worth a try before settling on a more expensive collar.

  • Affordable
  • Water resistant
  • Universal sizing fits any cat
  • Breakaway design


  • May not be effective for all cats
  • Can irritate the area around the collars

Unlike many other collars which have no odor at all or a light pleasant scent, these collars emit a robust citronella-like scent that not everyone can tolerate.

  • Affordable
  • Adjustable up to 14”
  • Natural active ingredients


  • Smells strongly
  • Doesn’t feature a breakaway design
  • Doesn’t last as long as many other methods

Our Top Pick

While each of these collars may be a good option for your pet, one collar emerged to the top, as it’s considerably more effective than all the competitors.

The Seresto collar from Bayer is the industry leader for a reason. It’s the most effective and longest lasting collar, and it’s preferred by many cat owners, and their cats as well.

If you’re not sure about dropping over $50 on a flea and tick collar for your pet, there are plenty of other, more affordable options you may consider. But, if you’re looking for the absolute best, most effective collar for your cat, you can’t go wrong with the Bayer Seresto.
