Best Flea Collars for Cats

Fleas are the bane of every cat owner especially when the warm season is fast approaching. Not to mention there are also ticks, mosquitoes, and mites, all of which are waiting in queue to take up residence on your cat. You need to deal with this problem immediately as these freeloaders carry harmful pathogens and thus, are capable of transmitting diseases to you and your pets. Fortunately, scientific advancement has paved the way for effective solutions.

The most convenient and cost-efficient solution to such dilemma is using a dependable flea collar that is specially calibrated to the needs of your feline companion. Flea collars nowadays exhibit incredible design improvements. Absorption-based collars, which are often considered as the best flea collars, boast an efficacy that can par with spot-on treatments. Opt for these collars since their formulation doesn't target a single area; instead, their chemical components are slowly released and then absorbed into the fat layer of your cat’s skin; hence, killing any parasite that feeds off your cat. Furthermore, the active ingredients spread across your cat’s whole body through its natural oils, killing all external parasites on contact.

If you are having a hard time figuring out which flea collar to choose among a plethora of options, know that we have put up together five of the best flea and tick collars for your beloved furry family member in this article review. We carefully researched each collar to save you from further guesswork and disappointment because the last thing you want is spending time and hard-earned money on an ineffective flea collar.

Choosing a Best Cat Flea Collar: What to Look for


The ingredients used in a flea collar should be the first thing to consider if you don’t want to waste your cat’s nine lives. It is general knowledge that you need conventional pesticides to effectively kill fleas and other parasites. Hence, it is wise to opt for a flea collar with approved chemicals to efficiently eliminate such parasitic freeloaders without triggering unpleasant reactions in your cat. It is also crucial that you only choose a flea collar that is recommended for your cat's age. An eight-month-old kitten, for instance, may find a flea collar designed for a one-year-old cat too potent and may fall ill.

If you want to be 100% sure that your pet’s health is unaffected by chemicals, you may opt for a flea collar using natural compounds. Organic collars use essential oils in the treatment and prevention of ticks and fleas without posing health risks towards your cat as well as your family.

Adjustability and Safety Mechanism

Adjustability is a feature pet owners should never overlook in a collar. The best flea collars for cats should be highly adjustable. Although many manufacturers produce collars with varying sizes, a one-size-fits-all collar is preferable: even cats under the same breed and has the same age may still vary in size.

Moreover, it would be best to choose one with a ‘breakaway strap’ to ensure your cat won’t get choked. The concern involving strangulation has led manufacturers to create flea collars with an automatic release mechanism, which allows your pet to free himself.


While a majority of flea collars are aimed at merely repelling fleas, you want a flea collar that can treat as well as prevent a wide range of external parasites. Ticks and mosquitoes carry a host of pathogens that are harmful to both human and animals.


Apart from a flea collar’s efficacy in eliminating external parasites, it should still be able to withstand your cat’s daily activities especially when you have an outdoorsy cat. The best flea collar should withstand constant exposure to the elements and would remain just as effective after constant exposure to water.


The longer duration a flea collar has, the better. You don’t want to replace your cat’s collar every two months. Make sure the active ingredients of the collar you choose don’t wear off before it’s expected time since there are plenty of flea collars that only work well during its first month.
