Best Flea Collar for Cats Reviews – Safest Collars for Cats to Kill Fleas and Natural Flea Collars for Kittens and Cats

A tick or flea infestation issue can be a menace for both you and your furry feline friend. Most cat owners—especially new ones—assume that fleas are a dog’s worst nightmare, but your feline companion is just as vulnerable to these ectoparasites. Using preventive treatments such as sprays and shampoos is effective when done in a timely manner, but flea collars work in the background and whenever your cat ventures in the great outdoors. With the seemingly endless selection of just about anything, even the task of picking the best flea collar for cats (and knowing which are the best cat flea collar brands) can seem complex. That’s why we’ve explored this space, compared features, and have narrowed down on the five best options that your feline will simply love you for.

While we only included the safest flea collar for cats in this review, it is extremely important to pay attention to the age and weight of your cat. Almost all chemical-based flea collars (some of which kill eggs and larvae too) can only be used when kittens reach 12 weeks old. You can get a natural flea collar for cats that uses essential oils for kittens, but you should still check with your vet — even if the package says safe for all ages. It is also important to note that most natural flea collars will only repel pests, not kill them.

So, what do you do if you have a kitten who is infested with fleas? The first thing to do is give them a bath. Dawn dish soap is a safe option. You can also use Espree Kitten Shampoo which is made from organically grown aloe vera or Burts Bees Tearless Kitten Shampoo with buttermilk. Next, you will want to use a fine toothed flea comb for cats to remove any remaining fleas, eggs, or debris. Finally, if your kitten weighs at least 1.5 pounds, you can apply a topical flea treatment to their skin. We have showcased ones that are good for kittens below.

Safe Flea Collars for Cats Guide – Natural Flea Repellant Cat Collars vs Flea Collar for Cats that Kill Eggs and Larvae Too

Just like dog flea collars and dog flea treatments, flea collars for cats can be extremely effective as long as you choose the best one. When affected by ticks and fleas, experts recommend keeping your cat indoors because your yard is already exposed to the little buggers, and preferably in a sturdy cat cage if you have carpets.

There are some things to consider before you head out shopping for the best flea collar for your cat, such as the age of your cat, length of the device, and duration of protection. You may also want to consider getting a water-resistant cat flea collar so that your cat is safe regardless of the weather conditions they wander off in.

Price

Prices of cat flea collars can vary considerably, and mostly depend on the features they come with. Cheap flea collars, for the most part, may only offer a month or so of protection, and are ideal only if your pet has been mildly affected by these parasites.

Apart from long-lasting protection, high-quality cat flea collars also ring in with some great features such as adjustable fit, breakaway design, and water resistance. While dogs don’t mind wearing collars, most cats don’t feel the same, and as a result try hard to break free from it. This is why paying the extra few $$$ for a breakaway cat flea collar makes sense, as it considerably reduces the chances of collar-related accidents.

Features

Flea collars for cats are available with several different features, so you should ideally choose one that works best for your pet rather than skimping out on the price. Chemical-free collars, also known as natural cat flea collars, are also available. Just as the name would suggest, they use natural ingredients such as rosemary oil.

Consider the following features for superior protection against ticks and fleas:

Age of cat – owing to the fact that felines have different strengths of immunity, it is important to check the age requirements of the respective cat flea collar.
Length of collar – just to be sure that the collar fits like a hand in glove, it’s a good idea to measure the circumference of your cat’s neck before buying one.
Parasite-specific collar – in the event that you know 100% what type of parasite is affecting your cat, you can buy a collar that’s designed exclusively for that issue.
Flea life cycle-specific – some cat flea collars are designed to target parasites at particular life cycles, and can possibly prevent re-infestation.
Duration of protection – flea collars may be good for one month, while others offer up to a year or more of protection.
Water-resistant – even if you live in an almost dry city such as Phoenix or Las Vegas, you never know when your cat can get wet, which can affect the chemicals within the flea collar.

Construction and Design

Cat flea collars are mostly crafted of plastic and are infused with ingredients, whether natural or chemical. Regardless of which type you buy, it’s important that you fit it properly so that it’s nice and snug with little excess to avoid having your pet bite into it and ingest the ingredients. The market now has flea collars made of natural oils containing rosemary and lavender that are known to repel ticks and fleas.

These collars work by distributing throughout your cat’s body, which kills the parasites that have already taken up residence and prevents infestation. Studies indicate that the best flea collars for cats can reduce fleas by over 95 percent and ticks by 90 percent over a period of roughly 6 months. There are several cat flea collars that are safe to use on kittens too—they just have safer ingredients than those for their older cousins.

Performance and Ease of Use

Flea collars for cats mostly come in standard sizes, but there are also long ones available so that you can customize it to fit your larger cat. Although the collars themselves do the job well, you can currently use topical flea control products, preferably sold by the same brand.

Further, some flea collars can irritate your cat’s neck and cause hair loss among other things, while others are extremely comfortable—so much so that your furry friend won’t even mind that it’s there. This is an important feature to watch out for.

Most cat flea collars are efficient at killing parasites, without causing any harm to your pets, but it’s a good idea to keep these insecticide-filled devices away from children just as you would with any insecticide.
