    Shopping guide for best flea collars for cats

    Last Updated December 2018

    You love your furry feline, but the fleas and ticks it brings into your home? Not so much. You could try a topical treatment, but you need to remember to reapply it monthly, and it can leave your cat’s coat feeling greasy. Fortunately, there’s another option: flea collars for cats.

    Cat flea collars do the same job as their topical counterparts. They keep fleas, ticks, and other unwanted pests away from your cat, but unlike topical products, collars last for several months at a time. But while this is one of the main benefits of choosing a flea collar for cats, it’s also the key reason you need to be cautious when choosing one. The wrong flea collar could end up doing your cat more harm than good.

    Here’s a guide to help you choose the best flea collar for your beloved pet.

    If you notice your cat licking or biting itself excessively, this could be a sign that it has fleas.

    Types of flea collars for cats

    Some flea collars kill both fleas and ticks while others may only kill fleas. In addition, some collars only work on the adult insects, enabling larvae to continue to grow and potentially irritate your cat even more. Think about which types of pests you’re having problems with and choose a flea collar that is designed to eliminate those insects. It’s best to choose a collar that takes care of juvenile fleas as well as adult fleas to stop the infestation in its tracks.

    • Active ingredients

    All cat flea collars should clearly list the active ingredients. Some common flea- and tick-killing agents include fipronil, imidacloprid, etofenprox, and flumethrin. A few collars are also made from natural essential oils like citronella. Some users argue that these natural collars are better for pets, while others argue that they don’t work as well. It’s up to you to decide which one you feel is better for your pet. Whichever type you choose, make sure you buy a feline flea collar. Dog flea collars can contain other ingredients that are toxic to cats.

    If your cat has sensitive skin, you’ll need to take special care when choosing a flea collar formula to make sure that your cat doesn’t have a reaction to it. But don’t just take the manufacturer’s word for it. “Hypoallergenic” is an unregulated term, and any manufacturer can make the claim without providing any proof to back it up. For a better measure of how hypoallergenic a flea collar is, consult customer reviews to see if any cats have had a reaction to it.

    • Age of cat

    Depending on the collar, you might need to wait until your cat is 8 to 12 weeks old before you can put the flea collar on him. Using it before the recommended age could hurt your still-growing kitten. Consult the manufacturer’s instructions to figure out if the collar you’re interested in is suitable for your cat’s age.

    Eight months of superior protection

    This Bayer Seresto collar kills fleas and ticks on contact and lasts for up to eight months. A quick-release mechanism prevents it from breaking or harming your cat in case your cat snags it on something. There’s no unpleasant odor, and as a bonus, the collar includes reflective clips to help you spot your cat in the dark.

    • Size

    The majority of flea collars for cats are adjustable so that they can fit just about any size cat. The collar should fit snugly on the cat without choking it. If you have a particularly large or small cat, you might want to check with the manufacturer to determine how large or small you can make the collar.

    • Material

    The flea collar should be made of a tough material that doesn’t break or tear easily. Otherwise, your cat could lose it and with it any protection it had against fleas or ticks. You can get some sense of how well a collar holds up by reading through customer reviews for the flea collar you’re interested in.

    • Protection length

    Flea collars for cats work for different periods of time. Some may only last three months while others last up to eight months. Consider the lifespan of the collar when considering its cost. If you want to compare two collars with different durations, price each of them out for a year and figure out which one offers the lower annual cost.

    • Water resistance

    A flea collar won’t do your cat any favors if the active ingredient dissolves as soon as your cat gets wet. This shouldn’t be an issue with most cat flea collars, but it’s a wise idea to verify this with the manufacturer before giving your cat a bath while wearing the collar or otherwise exposing it to water.

    EXPERT TIP

    Permethrin, a common ingredient in dog flea collars, is toxic to cats. Do not use a flea collar with this ingredient on your cat.

    EXPERT TIP

    The flea collar should be tight enough that your cat can’t lick it. Otherwise, your cat could end up with digestive issues.

    If your cat already has fleas, be sure to choose a collar that kills the adult insects instead of one that just repels new fleas.

    Flea collar prices

    Flea collars range in price from about $5 to nearly $50. But when evaluating your options, you can’t just look at the overall price. Some flea collars come in packs of two or three and some last longer than others. If you want an accurate comparison, you need to pay attention to the overall value. You can do this by pricing out each collar for a full year to assess which offers the lowest long-term costs.

    It’s worth noting that a higher price tag doesn’t always indicate a higher-quality or longer-lasting product. It’s better to evaluate your cat’s flea collar based on the protection it offers.

    Protect your cat for pennies a day

    This Hartz collar kills fleas, ticks, and their larvae to stop infestations in their tracks. Each collar lasts for seven months and can be used on all cats 12 weeks and older. It has a breakaway clasp and reflective material to keep your cat safe, and it resists water, so the collar keeps working even if your cat gets wet.

    Tips

    • Air out the collar if necessary. If the collar you choose has an unpleasant smell, you might want to air it out for a few days to allow this to dissipate before you put the collar on your cat.

    • Fit the collar correctly. Place the collar around your cat’s neck and tighten until it’s snug, then cut off any excess.

    • Monitor your cat for a few days. When using a new flea collar, it’s crucial that you keep an eye on your cat for the first few days to ensure that she isn’t having any adverse reactions to the formula.

    • Note when you put the collar on your cat. That way you’ll know when it needs replacing.

    • Put the collar on in the spring to guard against ticks. If you’re concerned about ticks, you should aim to put the flea collar on your cat by springtime, when the ticks are the worst. Fleas tend to be worse in the summer months.

    • Consult your veterinarian first if your cat is pregnant or nursing. You want to make sure the formula is safe for kittens.

    Other products we considered

    The five flea collars for cats listed above help to prevent against fleas and ticks, but if you’re concerned about other pests, including lice, ear mites, roundworms, and hookworms, the Rolf Club 3D Flea and Worm Collar for Cats might be a better fit. It protects your cat against 11 species of parasites, and each collar lasts for four months. It’s waterproof and odorless and is available in two sizes, one for kittens and small cats and one for medium and large cats. For those who prefer a more natural approach to cat flea management, try the TUZZE Flea and Tick Collar for Cats. This adjustable collar employs essential oil extracts to help deter pests without harming your cat. Each collar lasts for eight months and is backed by a lifetime manufacturer’s guarantee.

    Common essential oils used in natural flea collars for cats include citronella, lemon, eucalyptus, and cinnamon.

    FAQ

    Q. How do flea collars work?

    A. Flea collars work in one of two ways: they emit a scent that repels insects or they secrete a medication that seeps into your cat’s skin and kills fleas and ticks either on contact or when they bite your cat.

    Q. How long does it take a flea collar to work?

    A. Most flea collars begin killing fleas and ticks within 24 hours of application. However, this may vary from one collar to the next. Read the manufacturer’s instructions for specific advice on your cat’s flea collar.

    Q. Does my cat need to wear a flea collar all year round?

    A. That depends on where you live. In the southern United States, it’s possible for your cat to get fleas at any point throughout the year, but in the northern United States, your cat might not need to wear a flea collar in the winter.
