The 10 Best Flea Collars for Cats
1. Seresto Flea & Tick Collar for Cats — Best Overall
The Seresto Flea & Tick Collar for Cats is one of the most popular options on the market and for a good reason. It is one of the few veterinary-recommended prevention collars on the market. It can kill both fleas and ticks on contact. Cats and kittens of all weights can safely use this collar as long as they are older than 10 weeks.
It begins working within 24 hours, though many people noticed a difference in about 2 hours. It can repeal and kill ticks within 48 hours, though ticks that are already on your feline may die with 6. It kills on contact, which prevents tick-borne illnesses, as many will not have the opportunity to bite your feline.
The collar is extremely easy to adjust and is completely odorless. It doesn’t leave behind a greasy residue like some other collars. It has a quick-release feature that allows the collar to break off if your cat gets stuck on something. This prevents accidental strangulation and is extremely important for outdoor cats. The visibility reflectors also provide a bit of safety.
The formula on the collar is completely water-resistant and works for up to 8 months. You don’t have to worry about your cat getting caught in the rain or exposing the collar to too much sun.
2. Hartz UltraGuard Flea & Tick Collar for Cats — Best Value
Hartz UltraGuard Flea & Tick Collar for Cats is extremely inexpensive. It is a fraction of the price of many other options. It protects against both fleas and ticks for up to 7 months.
It is also completely water-resistant, so your cat can get it wet while exploring. This collar is made to withstand the antics of outdoor cats. It even has a breakaway snap, which can save your feline in the chance that they get stuck somewhere. This is potentially life-saving and recommended for any outdoor feline.
This collar can be safely used on cats and kittens over 12 weeks old. It doesn’t matter how much they weigh. Your cat can wear another collar alongside this one if necessary, which is great if your cat has an ID collar. The collar is scented, but not many people (or felines) complain about the smell.
Out of all the collars on this list, this Hartz option is the best flea collar for cats for the money.
3. Vet’s Best Flea & Tick Collar for Cats — Premium Choice
At first glance, the Vet’s Best Flea & Tick Collar for Cats may not seem that expensive. However, it only lasts for 4 months, which means that you’ll be purchasing it more often than other collars. Over time, this price can add up.
This collar is made in the U.S.A. using completely natural oils. It doesn’t have many of the harsh chemicals that some other options have, potentially making it safer for your feline. It is formulated with a mixture of peppermint and cedarwood oils, which can chase away pests. The collar is designed both to stop a current infestation and prevent new ones from occurring. It is one of the few collars that can actually stop a current infestation.
The collar is 20 inches and adjustable. If you have a large cat, this may be the only suitable option to fit them. It is effective against both fleas and ticks. The formula is water-resistant, so you won’t have to worry about it rubbing off or washing away.
4. Hartz UltraGuard Plus Flea & Tick Collar for Cats
The Hartz UltraGuard Plus Flea & Tick Collar for Cats is a “premium” option for the brand, which means it is slightly more expensive than its other models, though it doesn’t include that many extra features. But it is still a decent option.
This collar is designed to be worn by felines for up to 7 months. It kills and repels both fleas and ticks for complete prevention. It also stops flea eggs from hatching, effectively stopping the flea’s lifecycle and ending the infestation.
It has a breakaway design that will come apart if your feline gets caught on a branch or something similar. This prevents strangulation and makes the collar useable for outside cats. It is also adjustable. Some owners did complain about the scent, as this collar is not odorless.
5. Hartz UltraGuard PlusFlea & Tick Collar for Cats with Reflect-X Shield
The Hartz UltraGuard PlusFlea & Tick Collar for Cats with Reflect-X Shield is similar to other Hartz collars. However, it is a bit more expensive and comes with a reflective coating. This coating is designed to reflect light up to 450 feet away at night. It is designed primarily to make your feline more visible to passing cars. This works with varying degrees of success.
This collar is usable for all cats 12 weeks and older. It provides full-body protection from fleas and ticks for up to 7 months. The active ingredients slowly release, allowing it to spread out evenly over the cat’s fur. It is also effective against eggs, interrupting the flea lifecycle and preventing infestations. It is completely water-resistant, so you don’t have to worry about the formula coming off easily. This collar is made in the U.S.A. from domestic and imported materials.
The formula is completely non-greasy and can be worn alongside a normal collar if necessary. This is useful if your feline already has an ID collar.
Some owners did report that the breakaway feature was too sensitive. Some cats lost their collars quickly while simply roaming outdoors. A few people complained about the odor as well.
6. Adams Flea & Tick Collar for Cats
The Adams Flea & Tick Collar for Cats can kill fleas and ticks. It works on flea larvae and flea eggs, as well as adults. This helps prevent future infestations, as the eggs won’t hatch one day and cause another infestation. It works for up to 7 months. There are two collars included in each pack, which leaves you with a total of 14 months of protection for a decently low price.
The solution is completely odorless and non-greasy. It won’t leave a film on your cat’s fur. It also has a breakaway design, which can prevent your cat from losing oxygen if they get caught on a tree branch or something similar. This collar is easily made to size and can be used for cats over 12 weeks of age.
Some people did complain that this collar doesn’t work as well as advertised. It likely varies from cat to cat and may depend on external factors, like your climate. It doesn’t seem to be as effective as other options on the market.
7. Sentry PuurScriptions Flea & Tick Collar for Cats
Sentry is a well-known brand that produces several products for animals. However, its Sentry PuurScriptions Flea & Tick Collar for Cats is a bit disappointing. It does protect against fleas and ticks for 6 months, though this is somewhat shorter than most other options out there. It can also repeal mosquitos, but only for 1 month.
The adjustable sizing system allows it to fit on most cats. It is not suitable for cats under 6 months, though. This is a bit older than the cut-off for most brands. It isn’t particularly suitable for kittens. It contains an insect growth regulator that prevents eggs from hatching and larvae from growing correctly. This effectively ends infestations. However, it only works in this manner for 3 months. The collar states that it may take up to 30 days to break the flea’s lifecycle.
Some users do report that this collar is smelly. Indeed, it is scented, so it mostly depends on how sensitive you are to odor. There are also reports of the chemicals injuring cats. However, no recalls have been reported, so we are unsure how much of this is user error.
8. Zodiac Flea & Tick Collar for Cats
Compared to some other flea collars, the Zodiac Flea & Tick Collar for Cats is moderately priced. It works on fleas and ticks for 7 months, both killing and repealing them. It has a breakaway safety feature, so your feline won’t get stuck on something. It is water-resistant as well, allowing it to be used effectively on outdoor cats that might end up getting wet. This collar is made in the U.S.A., though it is unclear where exactly the ingredients and materials come from.
While this collar does seem effective at repealing small numbers of fleas and ticks, it does not effectively work against large infestations. If your cat already has fleas, you may want to look elsewhere for an appropriate collar. It may work on current infestations over time, but this may take as long as 2 weeks.
Some owners reported that their cats were sensitive to the chemicals in the collar, causing them to develop skin and fur problems. This probably depends on the cat, however.
9. Dr. Mercole Flea & Tick Collar for Cats
The Dr. Mercole Flea & Tick Collar for Cats claims to treat fleas and ticks on cats with natural oils. It works for about 4 months, which is much shorter than some other options. It isn’t cheap either so it will cost more over time. It does not contain any harsh chemicals or toxins, however. Instead, it is made with geranium, wintergreen, and almond oils. These form a barrier against pests, which don’t like the smell of the oils.
The collar fits necks up to 12 inches. It can be used on both cats and kittens as long as they are over 4 months old. It is made in the U.S.A. with no harsh chemicals or toxins.
That said, this is not a breakaway collar, so it is not safe to use on outdoor cats, which are most likely to come into contact with fleas and ticks. Some owners may not even like to use this collar on indoor cats, as you never know when your feline may get caught on something.
Many people reported that this collar didn’t work on their feline, anyway. In other cases, the collar appeared old and brittle and broke easily.
10. PetArmor Simple Source Flea & Ticks Cat Collar
The PetArmor Simple Source Flea & Ticks Cat Collar is suitable for kittens over 6 months of age. It can fit cats’ necks measuring up to 14 inches. This makes it useable for even large cats. It is all-natural and doesn’t contain the chemicals that are commonly found in other cat collars. Instead, it uses cinnamon oil, clove oil, and lemongrass oil. These ingredients are advertised to drive away fleas and ticks for up to 3 months.
The plant-based ingredients are safe to use around cats, children, and other pets. If you have dogs, this flea collar will not harm them.
That said, this collar lasts for much less time than other collars on the market. It isn’t particularly effective, though it does seem to work at least a little. The scent can be overwhelming at first, though it does wear off with time. The collar just needs to air out. It is a bit girthy, so it may not be suitable for much smaller cats.

Buyer’s Guide: How to Choose the Best Flea Collars for Cats
Choosing a flea collar for your cat can seem complicated. There are many different chemicals that each collar uses, and a variety of different features are available. Some may be more effective against preventing future infestations, while others are more effective against current infestations.
Here, we discuss all the features that you need to consider when choosing a flea collar for your feline.
How Do Cat Flea Collars Work?
There are several different types of flea collars. Some use medications and chemicals to drive away fleas and ticks. They do this by releasing toxic gases that will easily kill the fleas without injuring your feline. Others may do something similar, but with essential oils.
The effectiveness of the collar largely depends on the ingredients included. Pesticides are usually the most effective method. However, cats with sensitivities may be unable to wear these collars. They may irritate their skin and cause problems with their fur. Some cats may develop bald spots for this reason. Therefore, a natural collar with only essential oils may be the best option. These aren’t nearly as effective as regular flea collars, however.
Many flea collars can be effective against current infestations, though this isn’t always the case. Some collars can’t easily get rid of current fleas, especially if there are many of them. Instead, they work best when there is no current infestation.
Types of Cat Flea Collars
There are several types of cat flea collars, though they all work similarly. Some may work better in certain situations, though, so the type can be important when choosing the best option for your feline.
Liquid flea collars release a liquid onto your pet’s coat. This slowly gets worked into your cat’s fur through grooming and everyday activities. Typically, this is good at treating current flea infestations, since the fleas will come into direct contact with the liquid. However, it typically takes longer to work because the liquid has to be worked into the cat’s fur.
Gas collars emit a gas that drives the fleas away and is potentially toxic. These don’t leave anything on your cat’s fur because they work through the air. They are useful when repealing future fleas, but they may not be as good as getting rid of current ones. Some fleas may decide to tough it out and stay on your cat rather than jump away.
It can take weeks for the gas to kill current fleas in some cases, which is longer than most cat owners want to wait.
These collars are made with a soft resin that has chemicals mixed in them. These may be released as they come into contact with your cat’s body heat. They then slowly spread.
Solid-type collars have two different methods of dispensing their chemicals. One simply spreads the chemicals around on your cat’s skin. When the fleas come into contact with the chemicals, they die. This usually kills current infestations quickly. However, fleas must come into contact with your cat’s skin.
The other type soaks the chemicals into the upper layer of your cat’s skin. When the fleas bite, they automatically die. However, your cat has to be bitten first. These collars are typically less effective for this reason. Plus, if your cat is sensitive to flea bites, this won’t help them much.

The material of the collar matters too. It should be able to last for months. Otherwise, you won’t get full use of the chemicals located in the material. The collar can get put through quite a bit of wear-and-tear during this time.
The collar should also be water-resistant. Otherwise, it isn’t going to last for long. This is especially important for outdoor cats, but it is recommended for indoor cats as well.
Some flea collars are smelly. If it smells bad to us, it probably smells really bad to our cats due to their heightened senses. Often, gas-type collars are the smelliest because they’re releasing gases. Some collars may attempt to cover up this smell with added essential oils, like lavender, but even these nicer scents can be overwhelming.
Many collars will have a strong scent for the first 2 days. However, it typically begins to go away after that.
There are various types of closures that a flea collar can use. It is important for all outdoor cats to wear breakaway collars. These are designed to break when put under a great deal of force. This prevents the feline from being strangled should they get caught on a branch or something similar. Not all collars have this design, though many do. Be sure to check, especially if your cat goes outside.
Flea collars can last anywhere from 2 to 12 months. That is a huge range. The length of time that the collar lasts will directly affect its cost-effectiveness. Those that don’t last long will often cost you more in the long run. After all, you’ll have to purchase them more often. Be sure to keep this in mind when determining which collar to purchase. Just because it has a lower price tag doesn’t mean that it is actually cheaper.
