How to Choose the Best Flea Collar for Cats

Fleas are ectoparasites, which means that they bite and feed off the blood of their host. They are not only irritating because they cause constant biting and scratching, but they are also health-hazardous. Thus, if your cat has fleas and you don’t take any actions, then such diseases as tapeworms, cat flu, anemia, and flea allergy dermatitis can develop in cats. Thus, if you want to kill these parasites and prevent their reappearance, then search for the collar with the following characteristics.

      • Safety

Cat flea collars are considered to be great alternatives to flea medicines for cats, but you should know that the collar is safe. It is known that fleas are killed with different chemicals, but some of them can be very toxic both for cats and humans. So, search for the collar with non-toxic active ingredients so that they don’t trigger allergies or other unwanted reactions. Another solution is to go for the collars that have only natural ingredients such as different oils.

Also, the collar should have an easy release mechanism to prevent strangulation if your cat accidentally gets caught in the collar.

      • Waterproof qualities

When a flea collar is exposed to water, then its effectiveness can decrease over time. Besides, if the material is exposed to water constantly, it can wear off quickly. Thus, make sure that the collar is waterproof.

      • Durability

The collar should be durable so that the cat can wear it in different conditions and it won’t wear off quickly. Make sure that the manufacturer has used only high-quality materials. For instance, a polymer matrix composite is a popular option. The material is strong, stiff, and durable, but in the meantime, it is lightweight.

      • Adjustability

A perfect collar should be easy to adjust. It should be long so that you can put it on your cat and then cut the excess. Make sure the collar has enough room, but at the same time, it shouldn’t be too loose.

      • Operation time

Buy flea collars with a longer period of validity. Some collars offer protection starting from 3 months up to 8 months.

      • Price

Don’t go for the cheapest options, buy the product, which offers good quality at a certain price.

Types of Flea Collars for Cats

The type of the collar depends on the type of the insecticide used. In short, there are three major types.

An absorption-based type means that solid insecticide and resin are mixed so that the insecticide releases on the skin and fur over time. Also, there can be natural components: oils and herbs.

A gas-based type means that the liquid insecticide preparation releases as a gas. However, this type isn’t effective for eliminating fleas, it can be used only for preventing fleas.

A high-frequency type means that the collar emits ultrasonic sound waves to ward off the parasites.

Advantages of Flea Collars

More and more cat owners choose flea collars between the other alternatives to fight against parasites. Their choice is determined by the following advantages.

      • The collar is simple to handle;
      • The collar doesn’t make a mess;
      • Protection the collar offers is safe and effective;
      • There are adjustable lengths for different breeds of cats;
      • Protection is long-lasting, that is why it eliminates repeated doses;
      • It doesn’t contain chemicals, that is why the cat’s system doesn’t absorb them;
      • They are less expensive than spot-ons.

Active Ingredients In Flea Collars

There are the ingredients that flea collars should contain and the ingredients that you should avoid.

Active ingredients are the following:

      • Deltamethrin is considered to be one of the safest insecticides. This is a synthetic derivative of a naturally occurring pesticide called Pyrethrin. Though it is considered to be safe to use around humans, it is still neurotoxic to humans.
      • Amitraz is an effective anti-parasitic drug. It is a contact, non-systemic ectoparasiticide, which is commonly used in cats and dogs against external parasites: fleas, mites, and ticks.
      • Pyriproxyfen is a pyridine-based pesticide, which is used for flea control and flea prevention. It targets flea eggs and larvae.

While choosing the flea collar, steer clear of Tetrachlorvinphos (TCVP), which is harmful to humans and cats. It can cause such symptoms as dizziness, nausea, diarrhea. Also, Propoxur is another ingredient that affects the nervous system of fleas and ticks, and they die within 24 hours. It is highly toxic to humans, so wash your hands carefully afterward and don’t allow children playing with the collar with this chemical as it can cause dizziness, nausea, vomiting.


      • What is the best flea control for cats?

There are many methods to combat fleas (flea collars, shampoo, sprays, powder, comb, oral pills, flea drops), but flea collars for cats are the ultimate choice. They are easy to use and they offer protection for up to 8 months. Also, they don’t produce any mess and some types offer non-toxic chemicals. Besides, with a flea collar, you know that your cat won’t lick off any harmful medicine.

      • Do cat flea collars really work?

Yes, they really work. If your cat wears a flea collar, it will be protected from fleas for up to 9 months. It is easier to use compared to other means and it is less expensive. Besides, it is hassle-free and it is comfortable for long-term wear.

      • How does a flea collar work?

The flea collar kills fleas and prevents their reappearance. In fact, the collar can perform two basic functions. It can emit a gas that repels pests or emit active ingredients (chemicals or natural oils) that kill fleas and ticks before they bite.

      • How effective are flea collars for cats?

Usually, flea collars feature different active ingredients that give an instant relief and help your cat avoid the spread of new fleas. These components kill adult fleas, flea eggs within 24 hours, and this protection lasts from three months up to eight months. Besides, the flea collar doesn’t produce the mess compared to liquid drop treatments.

      • Are flea collars safe for cats and humans?

Usually, flea collars are considered to be safe for cats and humans, but it doesn’t mean that you shouldn’t take any precautionary measures. Thus, do not allow children to play with the collar because some insecticides in the collar can be toxic and dangerous for humans. Also, after you have petted the cat, just wash your hands afterward.

As for cats, some chemicals can cause allergy, and the pet can suffer from hair loss, redness around the neck, and sores. Besides, if the collar doesn’t have a safety release mechanism, then it can lead to strangulation.
