What to Look for in a Cat Flea Collar

Choosing the right flea collar can be a daunting task.

But have no fear, our detailed buyer’s guide will help you find the best flea collar for your cat.

Pick the Right Ingredients

A number of collars contain chemical compounds that boost their ability to kill parasites.

Some of these compounds include Amitraz, Deltamethrin, and Propoxur.

Then there are all-natural collars. These are safer, milder, and hypo-allergenic, which makes them more suitable for cats with sensitive skin.

A pro-tip: If you buy a collar with chemical compounds, make sure you stay away from Tetrachlorvinphos (TCVP). TCVP is an insecticide that effectively controls ticks, fleas, and other types of parasites.

Yet it’s a dangerous neurotoxin that can have harmful effects on both humans and animals. Some scientists even consider it to be linked to cancer.

Keep Your Cat Safe

Many cat owners worry about whether flea collars are safe.

While there are many that still contain chemicals, they won’t harm your cat by any means. Thanks to advancements in modern medicine, flea collars are now completely non-toxic and safe for year-round use.

Another safety feature that worries cat owners is the fear that the collar would strangle their cat. But collar manufacturers put an end to that problem by creating a ‘quick release’ safety mechanism.

If the collar got snagged on anything, this safety release mechanism allows your cat to disengage the collar himself. This way, he can get free without getting injured.

Long-Lasting Protection

Some collars will start delivering results in as little as 24 hours.

Others, however, need from 2 to 3 days before you can start seeing a difference in your cat’s fur. This depends on the type of collar, as well as its active ingredients.

When it comes to the overall lifespan, collars vary in their durability.

Some manufacturers claim that their collars offer protection for up to 6 months, others can last for 8 months. Then there are those that can last up to an entire year.

Again, this depends on the active ingredients. There are a few other factors that can decrease the efficacy like:

  • The collar constantly getting wet
  • Any type of damage to the collar, as breaking or snagging
  • An overly active and feisty cat

Find the Perfect Fit

Most flea collars are around 20 inches long.

This gives you the freedom of adjusting the size to suit your cat. So can you make those adjustments? Follow these steps:

  1. Put the collar around your cat’s neck and close the buckle.
  2. Place two fingers underneath the collar to make sure it’s loose enough around your cat’s neck.
  3. Leave anywhere from 2 to 3 inches after the buckle, and cut off the remaining extra piece.

Opt for a Water-Resistant Collar

When looking for a flea collar, try to find one that’s water-resistant.

Or better yet, find one that’s completely waterproof. Even though cats don’t like water, yours will probably get wet in some way or another.

Having a waterproof flea collar means you don’t have to worry about the collar losing its efficacy.

Get a Collar With a Wide Range of Efficacy

You need a flea collar that kills more than just fleas.

While there are those that get rid of fleas, ticks, and other pests, others go beyond that. Stronger active ingredients mean a collar can eliminate not only the basic types of parasites but also eggs and larvae.

It’s also important that you find a flea collar that can do two jobs: treat a flea infestation and prevent further ones from happening again.

The Verdict

You can find other treatments to get rid of your cat’s fleas, such as capsules and topical ointments.

Still, a lot of cat owners still consider flea collars as a reliable way of ending parasite infestations.

After reviewing the best cat flea collars, our top pick is the Seresto Cat Flea Collar. Its potent formula delivers quick and reliable results.

Even though it’s the most expensive, it’s also the most efficient. Another reason why we love the Seresto collar is its optional reflective clips. This a terrific feature to make sure your cat is safe at night.

Need something a little less pricey? Then check out our runner-up, the Fleebs Collar with Natural Essential Oils.

Its natural, plant-based unique formula ensures maximum protection and prevention of many types of parasites.
