Cats, just like all other pets, are vulnerable to fleas, ticks, and other parasites. As a caring pet parent, you need to adopt a method that can be used to control these annoying parasites and keep your cat healthy and happy.
With over 2000 different species of fleas, the Ctenocephalides felis is the most common one that is found in both cats and dogs. These tiny parasites create a home in your cat’s body and feed on his blood to survive.
A flea collar is one of the accessories that can be used to control fleas and ticks in cats and even dogs. You can use them to supplement other flea management techniques to get the best results overall.
Choosing the best flea collars for your cat is not the easiest thing to do especially when you have multiple cats to deal with. Every cat has his reaction towards a particular flea collar type and the chemicals used might prompt an allergic reaction.
Using the wrong flea collar on your cat can be dangerous because it can lead to health issues especially when the collar uses a toxic based chemical to control fleas.
Nowadays we even have a natural flea collar for cats as an option that is milder and safer to use. Either way, you need to know the product that will serve you best and keep your cat healthy in the long run.
We have gone through many products, did extensive research, and reviewed them just for you. Our buying guide on the 10 best flea collars in 2021 will help you narrow down to the product you want and provide solutions to the questions you might have.
How Do Cats Get Fleas and Ticks?
You know your home is super clean and well maintained, but you are wondering where your furry feline is getting all these annoying parasites from.
Indoor cats can get fleas from other pets or you can be the source too. Don’t get surprised. These little parasites might stick on your cloth or bag during the day in your outdoor errands and they may end up on your cat’s fur in the evening when you return home.
When your cat makes his outdoor adventures, he most likely will get fleas and ticks in many places out there including interactions with other pets and people.
This does not mean that you now deny him the chance to go out and have adventures. It however calls for your critical attention to where your feline friend spends his outdoor time. You can control this by ensuring that you walk him using a harness and leash whenever possible.
Once these little parasites get their way to your home, they can spread very fast by reproducing. They lay eggs on your cat’s coat which can then drop in different places in your home hence occasioning the spread.
One female flea is reported to lay about 2000 eggs in her lifetime. You, therefore, need to adopt a good method of flea control to remove them from your lovely cat and house at large.
How Do Flea Collars Work on Cats?
Just how do flea collars work on cats? Perhaps this is a question that has puzzled your mind and you are curious to know the answer. It’s quite simple. Flea collars work by emitting substances that are toxic to fleas and ticks.
Some work by emitting gases while others release liquids that spread on your cat’s skin, killing fleas and ticks found lodged on your cat’s body.
The ones that work by emitting gases are quite ineffective because it only eliminates fleas around the collar area. It is as well a dangerous mode of action because some toxic substances might also be toxic to your cat or other pets.
We have heard of previous cases where pets have died due to contact with the toxic substance used to control fleas.
The second way is more manageable, safe for use, and gets the work done almost perfectly. The video below from Elanco PetBasics summarizes the mode of action of flea collars.
Advantages Of Flea Collars
1. A safer way to control fleas and ticks
Flea collars with mild active ingredients provide a safer way to keep your cat free from fleas and ticks. This improves your cat’s hygiene and prevents him from getting diseases caused by the parasites.
2. Breaks the parasite’s cycles
Flea collars, through their active ingredients, are also able to destroy existing flea and ticks’ eggs hence breaking their cycle on your cat’s body.
With one flea collar, you can keep your cat clean for up to 8 months. This makes it an economical and effective way of controlling fleas on your cats.
4. Adjustable length
Most flea collars are adjustable and as such, it makes it easier to fit your cat well even when he grows bigger or loses weight.
Most modern flea and tick collars for cats are made with very lightweight material which is easier for them to walk around with. These collars do not add any burden on your cat’s neck when he wears them.
4 Main Types of Flea Collars for Cats
1. Absorption based
These types of flea collars have a more effective mode of action. They release insecticides that spread out on your cat’s body and get absorbed into his outer skin layer. This laces your cat’s entire body with insecticide which then eliminates the parasites from his body.
Absorption-based flea collars are more effective and they kill adult fleas, ticks, and offer additional protection to your cat for months.
Improved models of these types of flea collars have insecticides with Insect Growth Regulators which help prevent fleas from reproducing and reaching maturity stage.
These types of flea collars work by releasing gaseous insecticides which then eliminate fleas and ticks on your cat’s body. As we pointed out earlier, these types of collars are not very effective because they only work within a small range.
3. Natural flea collars
Natural flea collars for cats are made with essential oils, herbal and natural extracts. They are more suitable for cats who have allergic reactions to chemical-based flea collars. Many veterinarians agree that natural flea collars may not be as effective as their chemical-based counterparts.
4. Ultra-sonic flea collars
These collars work by emitting high-frequency noise of between 20 to 60 kHz. The noise is supposed to irritate the fleas and make them leave your cat’s body. It is a good option for those who are more concerned about using toxic substances on their cat’s body to control parasites.
A study by flea science concluded that ultra-sonic flea collars do not affect fleas in any noticeable way. If you choose to buy this type of flea collar for your cat, there is anecdotal evidence that shows it may work. We however recommend using it in supplement with other flea control measures.
What To Look for When Buying a Flea Collar for Cats
When shopping for a suitable flea collar for your cat, you need to consider several factors before making the final purchase decision.
1. Toxic to fleas while non-toxic to pets and humans
A good flea collar should get the job done by killing and repelling fleas from your cat’s body. A more potent one should break the cycles of parasites on your cat by destroying the larvae and preventing any of those little parasites from reaching maturity stage.
While it does all these, a good flea collar for cats should be non-toxic to both you and your cat. It should prevent NO health hazards when handling with your hands. Remember this is an accessory that releases substances to your cat’s body and is lodged on his neck. Imagine what an unsuitable variant will do to your feline friend.
2. The Scent Produced
The scent produced by a flea collar will certainly be the most noticeable feature neither you nor your cat can avoid. A sharp unpleasant smell may prompt you and your cat to cough which can later lead to health concerns.
Get a collar that produces a soothing sweet-smelling scent that will not compromise your comfort. The smell produced by the flea collar is a direct attribution of the ingredients used.
3. Is it water-resistant?
For a laid-back experience, you need to get a flea collar made with materials that are not affected by water. This is very handy when it comes to bathing your feline friend or when he is outdoors in the rain. You do not have to remove and put it back on every time your cat is exposed to water.
4. Emergency breakpoints
Having in mind that a flea collar is a worn accessory, you need one that ensures your cat remains safe whenever he encounters an emergency and more especially because flea collars are worn on the neck.
A breaking point in a flea collar is a weak point where it can break and tear whenever subjected to high strength. This can happen when your cat is on adventures and gets his flea collar attached to an external object. In an attempt to free himself, your cat’s pull force will trigger the collar to break making him free and safe.
Flea collars for cats have different price tags depending on several factors such as the units included in the package. The most common flea collars range from as low as $8 to as high as $60.
The ones that have a higher price also come with added perks aside from their basic core of controlling fleas and ticks. Just get the one that gets the job and fits your budget plan.
6. Is it Synthetic or Natural based?
The insecticides in flea collars that kill and repel fleas can either be synthetic or natural based. Synthetic chemical insecticides have long been associated with allergic reactions from cats and skin reactions.
The natural flea collar for cats is made with plant-based essential oils which have reduced association with allergic reactions and are safer.
We however cannot guarantee how your cat will react to any type of flea collar you use. Every cat has his reaction and it is caused by many factors including his pre-existing health condition.
All flea collars for cats have a form of adjustability that enables them to fit many cats of diverse sizes and ages. However, you should pick the one that is made with a material that does not loosen up too quickly when used. A good flea collar should be able to maintain the same size after several months.
