The 12 Best Cat Flea Collars of 2023

A cat flea collar is a strap with flea-killing active ingredients that is worn around a feline's neck. It contains a highly concentrated formula with these ingredients, which dissolve and spread evenly throughout the skin.

Eventually, these elements will get to the tail, effectively killing and repelling fleas from the cat's fur. This will help to reduce scratching, itching, and diseases caused by the parasites. With that in mind, here are the best cat flea collars to consider buying.

7 Best Cat Flea Collars: Review

1. Best Overall: Seresto 81857952

• Active Ingredients: Imidacloprid, Flumethrin
• Age Range Description: 10 weeks of age and older
• Scent: Odorless
• Item Weight: 3.52 oz.

As the best-selling cat flea collar, Seresto's 81857952 takes the best overall spot due to its effectiveness. It kills fleas and ticks using imidacloprid and flumethrin through contact, so no biting is required. These active ingredients spread slowly in low concentrations up to the tail.

That said, the collar begins to repel these parasites within 24 hours of application, and remains effective for a long 8-month period.

The product is vet-recommended and can be used on kittens that are at least 10 weeks of age. Additionally, it is odorless and non-greasy, which appeals to a wider range of cats in all life stages.

On the downside, the unit is expensive but is worth the money.

How to Buy the Best Cat Flea Collars

1. Active Ingredients

In any cat flea collar review, the most important factor to consider is the active ingredient(s). Whether one or many, they determine the safety and effectiveness of the collar.

If you are looking for a quick-action collar to get fleas under control in the shortest time possible, we recommend chemical or non-natural active ingredients. For this, you should check out Seresto's 81857952 .

However, if your feline is extremely sensitive, natural ingredients are best. Additionally, most are environmentally friendly and safe for humans. If you want such, we recommend Lordddon's flea collar .

2. Safety

There are two ways of looking at the safety factor. First is the presence of a breakaway buckle. This makes it easy for your cat to free himself whenever he gets stuck, and it can be found in Adams' Plus .

The second is low light visibility. Some collars have reflective straps to make your pet more visible in the dark. If your cat likes to run out at night, better get the Hartz Ultra Guard .

3. Adjustability

For a collar to work effectively, it must have a snug fit on your pet's neck. To achieve this, it must be adjustable.

Most collars come as a one-size-fits-all type, which is good if you don't know the exact measurements of your cat's neck. However, if you know these measurements, get a collar that has the perfect fit.

4. Water Resistance

Even though most cats don't like water, they might get wet, say if they are rained on outside or if you bathe them. As such, it is important to get a waterproof cat flea collar, which does not lose effectiveness when soaked.

5. Scent

A collar's scent should be picked based on personal preference or pet preference. If you are not sure about the smells that your feline likes and does not like, you should buy an odorless collar.

6. Duration

Each collar is designed to remain effective for a certain period. Some kill and repel pests for 4 months, while others go for as much as a whole year. Ultimately, the one that lasts longer is better because it means you won't have to buy a replacement for a while.

With that in mind, ShengKou's flea collar lasts for 12 months and we highly recommend it. That said, you should also consider the products that come as packs of two collars. Even if each one lasts for 7 months, you have 14 months in total if you have one feline friend.

Q&A

1. Are Flea Collars Safe for Cats and Humans?

This depends on the collar. Those with chemical-based active ingredients are not safe for humans and this can be a problem if you have kids at home. However, collars with natural essential oils as active ingredients are generally safer. As always, you should check the labels and user manuals to see if the collar is safe, especially for humans.

2. What Happens if a Cat Licks a Cat Flea Collar?

Again, this depends on the active ingredients. The situation will not be serious if the collar has hypoallergenic natural ingredients. However, chemicals can cause lethargy and seizures in severe cases if your pet is hypersensitive. Always check the active ingredients before buying.

3. When can a Cat Wear a Flea Collar?

If he/she has attained the age required to wear the specific collar. For some units, it is 10 weeks, while for others it can be as old as 16 weeks.

4. How Long Does It Take for a Flea Collar To Work on a Cat?

This depends on the ingredients. Some can begin killing and repelling within 24 hours, while others take up to 48 hours. Be sure to read the label before buying if you want a fast-acting formula.
