Seresto Tick and Flea Collar for Cats


Product Description

Seresto Tick and Flea Collar for Cats

The Seresto cat collar is a long lasting, tick & flear collar for cats and kittens providing up to 8 months of  continuous protection against fleas and ticks. Avoid the hassle of monthly topical treatments and save money in the long run with a Seresto collar.

Fleas are hardy and determined. They can be killed, but their resilience and 4-stage life cycle make it more difficult than most people want to believe. Additionally, the fact that fleas don’t spend most of their time on the pet makes the problem of locating them and wiping them out even harder. Seresto for Cats can solve the problem!

  • Protects for 8 months
  • Kills fleas, ticks and larvae
  • For kittens 10 weeks and older
  • Odorless
  • 3 visibility reflectors included


“What is Seresto®?”
A: Seresto® is a new treatment that offers combined tick and flea protection for cats for up to 8 months, with a single application. This means that you don’t have to worry about reapplication every month, while your cat enjoys continuous protection.

“What makes Seresto® different from other flea and tick collars?”
A: Seresto® includes innovative technology which enables it to release controlled doses of two active ingredients over long periods of time. These safe, low doses of active ingredients are transferred to your cat’s skin and hair, and spread across their entire body to fully protect your cat.

Seresto® is highly effective for up to 8 months with a single application. By overcoming the downsides of conventional collars, Seresto® is a true breakthrough.

“What are the active ingredients and how do they work?”
A: Seresto® contains two active ingredients: imidacloprid which kills adult fleas, flea larvae and lice – and flumethrin, which repels and kills adult ticks, larvae and nymphs. Together, imidacloprid and flumethrin deliver a significantly superior effect on insects than could be expected by adding together the efficacy of the two individual ingredients, as demonstrated in an in-vitro study2.

“I caught my cat chewing the collar, should I be concerned?”
A: Seresto® has been extensively tested for its safety, including pets chewing on the collar or ingesting the entire collar. As the vast majority of active ingredients are bound in the collar matrix and not on the surface, the only side effect recorded after ingesting a full collar was a mild stomach upset (e.g. loose stools), which was resolved within 24 hours.

To prevent your cat from chewing the collar again, you might want to reattach it slightly more tightly. Please click here for more information.

“Is Seresto® safe for kittens?”
A: Seresto® is safe for use in kittens aged 10 weeks of age and older.

“How long do I have to wait after having applied a spot-on before I can use Seresto®?”
A: There is no need to wait between applications. Seresto® can be applied immediately after spot-on application.

“Should there be a time gap between taking off an old collar and putting on a new one?”
A: No, due to its low-dose, controlled-release technology the new collar can be applied immediately.

“Seresto® does not smell. Does this mean that there are not sufficient active ingredients on the surface for it to be effective?”
A: No. Seresto® uses different ingredients than traditional collars – combined with innovative technology and the way the ingredients are released – means that Seresto® protects cats without the unpleasant smell of older generation collars.

“With traditional collars, manufacturers often recommended to “stretch” the collar in order to activate it. Do I have to do the same with Seresto®?”
A: Stretching the collar for activation is not necessary with Seresto®. Just follow the application instructions here and Seresto® provides the pet with immediate protection against fleas and with repellent protection against ticks within 48 hours.

“Promising quicker onset of efficacy, other collars often recommend brushing the collar against the cat’s spine and belly, starting from the tail before applying it. Should I do the same with Seresto®?”
A: Seresto® has a very quick onset of efficacy, which is why this step is not required for Seresto®. After application, Seresto® provides the cat with immediate protection against fleas and with repellent protection against ticks within 48 hours.

“What should I do if the collar becomes covered in dirt? Can this impair the efficacy of Seresto®?”
A: Bayer is not aware of dirt having an impact on the release of active ingredients in Seresto®and hence its efficacy. If the collar should become dirty, it can simply be wiped down with a moist cloth.

“Can the Seresto® collar be used alongside normal collars? Will it damage them?”
A: Seresto can be used alongside normal collars without damaging them.

“Why does Seresto® have a white powder on the surface, when taken from the pouch?”
A: Stearic acid is one of the components of the collar and may appear as a white layer on the surface of the collar. It is a lubricant for the easy release of the collar from its mold after the production process. Stearic acid is safe and is also graded for use in food, i.e. as a hardener in confectionary. Therefore, the white powder is not of concern and can simply be wiped off, if desired.

“Can I attach items (such as a leash or name tag) to the Seresto®collar?”
A: Seresto® has been tested with safety reflectors specially developed for Bayer collars. They are safe and do not interfere with the product’s efficacy, hence they can be used and attached to Seresto®. For any other item, such as a name tag, no testing was conducted and so it is not recommended, especially if the tag covers the surface of the collar. It is important that any item, if attached (including reflectors) is only applied on the non-overlapping part of the collar in order not to block the safety mechanism. Leashes should not be attached to the collar in any case, as the force of the pulling cat would open the collar’s safety mechanism.

“How often should you check the tightness of the Seresto® collar on a growing kitten?”
A: There is no universal answer, as kittens grow at different rates, but we recommend frequent checks of the collar and readjustment if necessary.

“Can I remove the collar after a couple of months and reapply it the next year? Will it still work?”
A: Bayer strongly discourages pet owners from doing this, as it has not been tested and might have an impact on the level of protection pets receive. For the best protection of your cat, Seresto® should be used all year round. However, if Seresto® has to be removed temporarily, it can be reapplied to the cat without any problems.

“Do I need to remove the collar if my cat gets wet?”
A: No, the Seresto® collar itself is water resistant. Also, because the active ingredients are stored in and distributed through a layer of oil on the pet’s skin, being wet won’t wash them away.

“How should I dispose of Seresto®?”
A: Unused collars or any remnants of the collar should be disposed of in accordance with local requirements.
