Description
Seresto Flea Collar
Seresto is an innovative collar that protects cats for up to 8 months against fleas and ticks.
Functioning
Seresto contains the active ingredients imidacloprid and flumethrin. The Seresto collar works against adult fleas for 7 to 8 months and against flea larvae for 8 months. Against ticks, the Seresto collar works for 8 months. Additionally, Seresto has a repellent effect against ticks. This repellent effect prevents ticks from feeding on your cat, thereby significantly reducing the risk of tick-transmitted diseases. Furthermore, Seresto reduces the risk of infection with Leishmania infantum transmitted by sandflies for up to 8 months. Seresto does not work against mites.
The collar is for external use only, is water-resistant, and odorless. Thanks to the special “polymer matrix” of the collar, the highest concentration of active ingredients is inside the collar, while the concentration on the outside of the collar is much lower. This makes the Seresto collar very safe to use. Therefore, Seresto is also safe for other animals and children. The active ingredient is not located on the outside of the collar but adheres to the sebum layer of the skin. Hence, the collar is considered safe. This has also been confirmed by a series of safety studies conducted among users. Therefore, the animal can be safely petted after applying the collar. However, ensure that a child does not hold the collar for more than 15-20 minutes. The Seresto collar for cats contains a special safety mechanism that ensures the collar comes loose or breaks if the cat gets stuck.
Usage
Seresto can be used on kittens from 10 weeks of age. However, note that kittens grow fast, so loosen the collar in time.
When applying the collar, it is important to remove the remnants of the plastic connecting pieces on the inside of the collar. Then, place the collar around your cat’s neck, without tightening it too much (leave about two fingers’ space between the neck and the collar). Then, pass the excess collar through the loop and cut this piece off, leaving 2 cm. After applying the collar, the active ingredients will then spread over the rest of the cat’s body.

Helps really!
I use the bands for cats and dogs. They are all outdoors a lot and fleas and ticks are a thing of the past! Meanwhile, some acquaintances are also using it and are similarly convinced!

• The second hook to tuck the strap behind doesn’t work well, the strap often comes out from there.

Best remedy against fleas and ticks
My cat was constantly getting ticks as an outdoor cat and once even had a serious flea infestation. Other products didn’t help with that. I got this collar from the vet for the first time, and immediately there was peace from the pests. I have purchased the collar here several times since then, and the same result every time. I put the collar on the cat at the end of February/beginning of March, and the effect lasts until the next change. This product is excellent, and I can only recommend it.

Kat Castle, 5 years, Maine coon, 6 kg
• I give the product Seresto a 7 (scale 1-10).
• The best feature of Seresto I find is the long duration of action (7-8 months).
• I was very satisfied at first, bought one for my other cat as well. However, she only had it on for less than 2 days and lost it… and I find them way too expensive for that to happen. The maine coon has become a bit balder around his neck, but because they last so long I didn’t even mind that at first.

• I was initially very satisfied, bought one for my other cat too. However, that one didn’t have it for even 2 days and lost it… and I find them far too expensive for that… to lose so easily. The Maine Coon has become a bit thinner in his neck, but since they last so long, I didn’t even mind that at first.

Best way to combat fleas and ticks
My cat, as a free-roaming animal, constantly had ticks and even experienced a significant flea infestation once. Other methods could not tackle this issue. I first obtained this collar from the veterinarian, and immediately, there was peace from the pests. I’ve bought the collar here several times since then, and the result has been the same each time. I put the collar on the cat at the end of February/beginning of March, and the effect lasts until the next change. This product is excellent, and I can only recommend it.

Flea collar
Twice a year they get a new collar and are therefore flea-free. I and the kittens are very happy about it.
Very effective against ticks
on with the collar and the cat (Main Coon) can go a year before the first tick settles again – fantastic and that in forest and long grass surroundings.

Finally, our cats are tick-free again, and I can let them into bed with the children without worry.
Works well
Wild deer pass through our garden, so there are many ticks here. Last summer the Seresto collar pretty much protected our cat, so I bought a new one for this season.
Very effective
Look at my review 10 May 2023
We have used Seresto for several years and it lasts for a year on our cat. We are very satisfied 🙂
Very satisfied
My cat doesn’t tolerate some flea treatments well, and against others the fleas seem to have become resistant. With this collar, he is doing very well! This is really a recommendation!
Very good product
Since our cats started wearing this collar, they have a maximum of 1 tick per year. Previously, they had very many ticks. We live in the countryside. It is the best remedy against ticks. We have been using it for many years.
