Seresto® collar for cats
Long-lasting protection from fleas and ticks
One collar against fleas and ticks

Fleas and ticks can quickly become a problem for you and for your cat if you don't stay on top of things. But it’s easy to forget to give regular, monthly treatments. The Seresto® collar for cats keeps your pet protected for up to eight months at a time.

The Seresto® cat collar kills ticks and fleas through simple contact, which means they don't have to bite your cat before they’re affected. No biting means no itching and giving your cat the needed protection. If the parasites aren’t biting and sucking blood, there is a reduced risk of transmitting infections, which means you can put Seresto® on and simply know that your cat is well protected. This makes Seresto® the easy and long-lasting way to help your cat stay happy, healthy and itch-free.

How does it work?

At first sight, Seresto® might look like just another pet collar, but it’s a long way from being ordinary. Unlike other flea and tick collars, Seresto consists of a polymer matrix that slowly releases controlled doses of two active ingredients called imidacloprid and flumethrin. The collar works to build up an invisible layer of protection that kills fleas and repels and kills ticks that come into contact with your cat.

What is Seresto?

Seresto is an innovative collar that protects your cat from ticks and fleas for up to eight months. This means that you don’t have to worry about more frequent applications of flea and tick treatments, and there is no risk of forgetting to do so.

What makes Seresto different from other flea and tick collars?

Innovative technology enables the collar to release controlled, safe doses of its active ingredients over long periods of time. These are transferred to your cat’s skin and fur, and spread across her entire body to keep her protected from ticks and fleas for up to eight months

What are the active ingredients in Seresto?

There are two: imidacloprid, which kills adult fleas and flea larvae; and flumethrin, which repels and kills all life stages of ticks. Both ingredients act on contact without the need to bite.

Why am I still seeing a tick on my cat when she’s wearing a Seresto collar?

Ticks may still grab onto your cat’s coat when she brushes past them, even if she’s wearing a Seresto collar. The active ingredients work on contact, which means the ticks need to grab onto the fur to get exposed to the active ingredient. However, once they have climbed on, the ticks will fall off and die. You may therefore sometimes also see ticks tangled in your cat’s fur.

My pet has started chewing the collar, should I be worried?

As the vast majority of active ingredients are bound in the collar matrix and not on the surface, they are not released or absorbed when the collar gets chewed. If any, mild gastrointestinal signs may be seen. Nevertheless, you should avoid chewing,and if your cat manages to get her own collar into her mouth it’s likely that it is applied too loosely. Ideally two fingers fit between the collar and your cat’s neck.

Is Seresto safe for kittens?

It’s safe for use on kittens aged 10 weeks and older when used as directed.

Should I leave a gap between taking off an old collar and putting on a new one?

No. It's even important to put it on without any delay to assure a continuous protection of your cat.

My Seresto collar doesn’t smell at all. Does this mean it’s not working properly?

Not at all. Seresto is odourless, which means you don't have to put up with any of the unpleasant smells you usually associate with older flea and tick collars.

Other flea and tick collars require stretching to activate them. Do I have to do this for Seresto?

No. Stretching the collar for activation is not necessary. Seresto’s efficacy against fleas and ticks is reached within 48 hours after application of the collar to your pet.

Can the Seresto collar be used alongside normal collars?

Absolutely. Seresto can be worn alongside your cat’s usual collar without compromising its efficacy, as long as contact with hair and skin is evident.

My cat is scratching at the collar, causing redness and irritation. What should I do?

If your cat isn’t used to wearing a collar, there is a slim chance that she might develop mild reactions such as scratching, redness and hair loss. These symptoms usually disappear within one to two weeks, without removing the collar, as your cat gets used to wearing it. In some cases, temporary collar removal may be recommended until the symptoms have disappeared. In rare cases in cats, application site reactions such as dermatitis, inflammation, eczema or lesions may occur and in these instances, collar removal is recommended. Please consult your vet if the symptoms persist or become more severe.

What should I do if the collar gets dirty? Will a muddy collar still keep my cat protected from fleas and ticks?

We are not aware of mud having an impact on the release of the active ingredients in Seresto and hence its efficacy. If the collar does get dirty, you can simply wipe it down with a moist cloth.

Can I attach a nametag to my Seresto collar?

Seresto has not been specifically tested with such items, so we do not recommend attaching accessories to your cat’s Seresto collar, especially if such accessories cover the collar’s surface.

Is Seresto cat collar water-resistant? Do I need to remove the collar if my cat gets wet??

Seresto does not need to be removed when a cat gets wet or is bathed. The active ingredients are contained in the collar matrix and will not be released into water. They spread through the lipid layer of the cat's skin and hair and even if this lipid layer is partially washed off by bathing, Seresto will quickly replenish the active ingredients and the pet will be protected again.

However, prolonged, intense exposure to water or extensive shampooing should be avoided as the duration of activity may be reduced.

What happens if my cat gets her collar stuck on something?

Seresto is designed with a double safety-release mechanism. In the unlikely event of your cat being trapped, the collar will widen when she gives a hard pull, allowing for a quick release. The collar is also equipped with a predetermined breaking point, so a harder pull will break it.

How often should I check the fit of the Seresto® collar on a growing kitten?

Kittens grow at different rates and we recommend frequent checks of the collar and readjustment if necessary. Watch the video above to see how to fit your Seresto collar properly, and always follow the guidance provided.

Can I remove the collar for a couple of months and reapply it later? Will it still work?

This hasn’t been tested and it might have an impact on the level of protection your pet receives. Therefore we strongly discourage you from doing this. For the best flea and tick protection, Seresto should be used continuously and ideally all year round. However, we do not see any problem if you temporarily need to remove the collar (e.g. during grooming).

How should I dispose of a Seresto cat collar?

Used collars or any remnants should be disposed of in accordance with local requirements. The product should not enter water courses.
