If you’re wondering what is the best flea and tick collar for cats you’ve come to the right place. In this post you’ll discover if flea collars really work compared to spot on treatments or pills. Plus, what you need to look for when choosing a collar and lots more.
Many flea and tick collars for cats contain harsh chemicals designed to kill fleas. Sometimes these can irritate the skin and even cause fur loss.
However, most of the flea collars I’ve shared with you here have natural ingredients with no pesticides. To be honest I’ve never bought flea collars as only ever used spot on treatments.
That being said, the ones you’ll find here have good reviews. Whether you’ve previously tried solutions that don’t work, or looking for a natural product I hope you find this post useful.
How flea collars work

Older type of flea collar tend to have a thin coating of ingredients and often lack safety features. The chemicals may work effectively at killing fleas at close distance, but don’t work consistently.
This is because only fleas or ticks close to the animals neck will be killed. Those further away on the body may not be affected.
In addition, if you touch the collar you’ll probably get some of the chemicals on your hands. Also, over time, the collar will become less effective and need replacing.
There are two types of flea collar. The first kills fleas on contact. This means your cat won’t get bitten.
The second type works by releasing chemicals absorbed into your cats’s skin. Any fleas that bite your cat die from insecticide poisoning.
One of the main benefits of flea collars is they’re often less expensive than spot on treatments. In addition, while spot on is only effective for around 30 days, collars can remain effective for for up to eight months.
What you need to consider when buying a flea collar for your cat
The number one consideration should always be safety. NEVER buy collars that don’t have safety release mechanisms.
If you have young children that enjoy petting the cat it’s possible they’ll be exposed to harmful chemicals. Not only that, but your cat will be exposed to them as well!
Natural alternatives
Though insecticides are very effective at killing fleas, you don’t want your cat to suffer any potential side effects. These chemicals are toxic and could cause skin irritation.
While most natural flea collars won’t provide complete protection, they will help. Although, if you have a multi-pet household you’ll probably want to combine with other flea treatments.
Even if your cat spends all her time indoors she can still get fleas. This is because flea eggs can be carried indoors on the soles of shoes, other pet’s fur, or many other ways.
So if you’re asking, “do indoor cats get fleas?” the answer is YES! The following flea and tick collars for cats are based on my own opinions and customer ratings. I may make a small commission on any sales made but this in no way reflects the price you pay.

Hi Kathy, thank you for doing the research and sharing all these options. I prefer the natural flea collars, as I love anything natural. Moreover, it wouldn’t cause harm to anyone.
Hi Muslimah, thank you for your comment and glad you enjoyed this post about flea and tick collars. I also prefer using natural products whenever possible as they’re safe for both pets and people. Thanks for stopping by:)
Hey Kathy, thanks for sharing this post. The season of fleas and ticks is starting again. I found collars to be the best solution for repealing these insects from our cats. THe worst thing that happens is that they lose it. We never had any other problems with any of the collars that we bought them. I found some interesting recommendations here and I will check out Vet’s Best 4-month Flea and Tick Collar for Cats. Seems like it’s got the least cons. Thanks for sharing another very informative post!
Hi Ivan. thank you for your comment and glad you enjoyed this post:) Yes, Spring is when fleas and ticks seem more active. I know what you mean about flea collars getting lost! Vet’s best is a good choice, especially as the ingredients are natural. Essential oils can be very effective in eliminating fleas and ticks.
Hi Kathy,
I don’t know there are natural collars in the market, and it’s never too late to learn new stuff today. I love the first few recommendations are made with natural ingredients, and they are also waterproof & at least 4-month lasting.
For me, my top pick is the MonipGu one since it’s 8-month lasting. However, I am also wary because the company doesn’t reveal what the ingredients are, and it’s better to share more details on this part. You will also get a flea comb as a gift, so I still prefer this one.
Cheers,
Matt
Hi Matt, thank you for your comment and glad you found this post useful:) I also like the natural flea collars especially as they’re also waterproof. Yes, the Monipgu flea collar is a good choice, especially as it has a safety release feature. I agree, they should disclose the ingredients, but at least Monipgu claim they’re natural. Thanks for stopping by:)
Hi Kathy
The cat flea collar reminds of a wrist band insect repellent I owned a fears back, it was effective but after a short while it wasn’t effective anymore maybe because it wasn’t meant to be used for a long time.
When buying a cat flea collar I will definitely look out for one that has natural components or ingredients, one that is effective and one that my cat can use for long so that I can save money and will not have to be changing that collar regularly. Thank you Kathy Joyce for this amazing article. Cheers
Hi Femi, thank you for your comment, and glad you enjoyed this post about flea collars. Your insect repellent wristband sounded interesting. Sadly, you’re right, these things aren’t designed to last for long. Yes, definitely consider natural cat flea collars. Most of the one’s I’ve shared here claim to last up to 4 months, which isn’t at all bad:)
