Seresto® for cats kills and repels fleas and ticks for 8 months in an easy-to-use, odorless, non-greasy collar.

You'll both appreciate 8 months of continuous flea and tick protection.

Cats are independent by nature, but they still need your help with flea and tick protection. Seresto® for cats is designed to be a convenient way for you to help protect your cat from fleas and ticks that can cause bites.

Our innovative Sustained Release Technology provides protection from fleas and ticks for 8 continuous months in each non-greasy collar. That's one easy-to-use collar instead of 8 monthly treatments.

seresto-8mnth Truly unique technology for your cat.

Seresto® is a unique polymer matrix collar that offers a continuous supply of two active ingredients: imidacloprid and flumethrin for effective 8-month protection against fleas and ticks. That's one convenient, non-greasy, odorless flea and tick collar instead of 8 monthly treatments.

The active ingredients are stored within the collar. They are released in low concentrations and are distributed over the pet's hair and skin surface for 8 months. As active ingredients wear off over time, the Seresto® flea collar for cats continuously replenishes the skin and hair coat with a new supply of active ingredients. Fleas and ticks are killed through contact with the active ingredients - no biting required.

For 8 month prevention and treatment of fleas and ticks on cats and kittens 10 weeks of age and older:
  • REPELS AND kills fleas and ticks
  • Repels and kills ticks for 8 months, including Deer ticks (vector of Lyme disease and anaplasmosis), American dog ticks (vector of Rocky Mountain spotted fever, cytauxzoonosis and ehrlichiosis), brown dog ticks (vector of ehlichiosis, anaplasmosis, babesiosis, and Rocky Mountain spotted fecer), and Lone Starticks (vector of cytauxzoonosis and ehrlichiosis).
  • Prevent tick infestations within 48 hours after application.
  • Quickly kills fleas on cats within 24 hours and continues to prevent infestation for 8 months.
  • Treatment with Seresto kills fleas that may vector bartonellosis (Bartonella henselae), tapeworm infections (dipylidium caninum), feline infectious anemia (Mycoplasma spp.), and rickettsiosis (Rickettsia felis).
  • Re-infesting fleas are killed within 2 hours with protection against further flea infestation lasting 8 months.
  • Kills and repels fleas before they lay eggs.
  • Seresto aids in control of flea larvae in the cat's surroundings following contact with a Seresto-treatd cat.
  • Bayer Polymer Matrix ensures that both active ingredients are continuously released in low concentrations.
  • Make sure to replace the collar after 8 mounts for year-round tick and flea pest prevention.
  • Light reflectors for added visibility in the evening and at night.
  • Ingredients

    Imidacloprid 10.0%
    Total 100.0%

    Useful Information

    One collar per animal to be fastened around the neck. Remove collar from bag directly before use. Unroll collar and make sure that there no remnants from the plastic connectors inside the collar.

  • Insert end of the collar through the buckle. Adjust the collar around the animal's neck without tightening it too tight or leaving it too loose.

  • As a guide, it should be possible to only insert 2 fingers comfortably between the collar and the neck.

  • Pull excess collar thru the loop(s). Collar length of greater that 1 inch (2cm) beyond the loop(s) should be cut off unless it is on a growing puppy, where some additional length may be needed for adjustment as the animal grows.

  • After application of the collar, three reflector clips may be fixed permanently to the collar to increase the animal's visibility in the dark. Take the clips out of the bag. The clips should be evenly distributed on the non-overlapping part of the collar. The clips are correctly applied when a clicking sound is heard. For safety reasons once the reflectors are fixed to the collar the clasp closes permanently and cannot be re-opened.

  • The collar should be worn continuously for the 8 month protection period. Check periodically and adjust fit if necessary, especially when puppies are rapidly growing. Rarely, mild application site reactions may occur, such as scratching, redmess and hairloss, which usually recover within 1-2 weeks without the need for collar removal. In some cases, temporary collar removal and bathing may be recommended until symptoms have disappeared. In very rare cases, application site reactions, such as dermatitis, inflammation, eczema or lesions may occur. In these instances, immediately. If your animal is on medicaiton, consult your veterinarian before using this or any other product.

    This collar is designed with a release mechanism. In the unlikely event of a dog being trapped, the dog's own strength is sufficient to widen the collar to allow for quick release. Replace the collar after 8 months for optimal tick and flea protection.

    It is a violation of federal Law to use this product in a manner inconsistent with its labeling. Do not contaminate feed or food.

    Occasionally slight itching may be observed in animals that are not used to wearing collars in the first few days after fitting. ensure that the collar is not fitted too tightly. Slight hair loss and mild skin reactions due to the mechanical irritation of the collar may occur at the application site which usually recover within 1 or 2 weeks without the need for collar removal. For further guidance regarding individual animal sensitivities. In case of loss of collar, a new collar may be applied immediately. Do not attach a leash to the collar as this may cause breakage.

    Keep the collar in the bag and in the outer packaging until use. As with any pesticide product, do not allow small children to play with the collar or reflectors, or to put them into their mouths. Avoid contact with eyes, skin or clothing. Wash thoroughly with soap and cold water after fitting the collar. People with sensitivity reactions to the ingredients of the collar should avoid contact with the collar. Choking hazard. Contains small parts. Do not place collar or reflectors in mouth. Not intended for use on humans.

    I love it.
    I have 3 cats I've been using Front LIne on for fleas. After the August application, I started seeing fleas when I combed them. Lots of fleas. A friend had gotten her cat a Seresto Flea Collar and was very happy with the results. So I decided to try it. Got one for each cat, and now find no fleas when I use the flea comb on them. Very happy with the results. And thrilled that they last 8 months, so I don't have to reapply every month like my last flea product.

    Best Flea & Tick Collar there is out there!!
    This is the second time I purchased the product through your company. This second time, the product was made more cheaply, one of the 3 pieces you add onto the collar came broken, and overall I don't think it should have cost the same as purchased last year. I am hoping it does as good of job as the one the year before. One pic of father cat on work computer. Sorry, no children!!

    Seresto Collar
    I was looking for an alternative to liquid vials of tick& flea protection, so this is the 1st time I have used the Seresto collar. It's still early in the season, but so far there have been NO TICKS on my 3 cats. I priced searched and Entirely Pets with the coupon code I had was definitely the lowest cost. I wish the collar was a bit smaller, on all 3 cats I had to cut the left over strap and it does not seem to stay in the loop very well, but if it keeps them and I tick free that's all that matters.

    Great Choice
    Good product. Purchase the 3 pack for the cats but unfortunately one had a reaction to the collar around his neck, causing a sore to appear, so he is not able to wear one.

    Good Product
    These collars work great. Better than topicals. I put the topicals on my cats and they were useless. My vet said some needed to be reapplied as often as every fifteen days.
    Just make sure you get the collars tight enough. I made that mistake the first time around.

    This is a fabulous product for my cats and the dog has one too. It is easily worn and none of them are bothered by it Every vet trip confirms no parasites of any kind on any of the animals. I thank Seresto for that as I live in the woods.

    All three cats now flea free
    I have had an ongoing problem with fleas ever since moving to the area I'm in now. We'd been using Advatage II for several years on recommendation from our vet and it had been successful - even though at that point I was also living with a roommate's mostly outdoor, but in at night dog. After moving, all cats remained indoors, and there were no "outdoor" pets. But the fleas were persistent. Vacuuming every other day, having the house treated by a professional every spring, and the Advantage II were just no match. The constant scratching, bald patches, and fleas in our furniture/beds/linens were just unrelenting. We even tried diatomaceous earth in our desperation (this absolutely just made a mess, we're still finding powder in dark corners of the house a year later). Our vet was reluctant to switch because there are known instances of some pets reacting to this medication (in particular one of my cats has a very bad reaction to some flea dip/shampoo products), but said that we might want to try this. We put it on all three cats, immediately after a two day cycle of vacuuming and pest treatment for the house, and I'm absolutely amazed at how quickly a two year issue just evaporated. We watched closely for adverse effects, but not one of my cats had any noticeable side effect.They didn't even seem to mind wearing them - even now not one of the three has removed the collar. There was minor resurgence a few weeks later (one or two fleas spotted live on the cats) but I haven't seen one since. We're nearly five months in and nearing the end of the serious flea season in our area and I'm relieved to say still no fleas. We are still keeping up on the vacuuming (cut back to once a week though) and will probably have the house treated again in the spring, just to be on the safe side. But regardless, it was entirely worth the price - the same amount of time on Advantage II plus all the additional measure would have cost quite a bit more than what I spent on this.

    Great purchase
    My cats have been scratching constantly. Didn't think it was from fleas because I didn't see any on them. After I got the collars they both stopped so it goes to show you fleas HIDE. haha
    I love the collars, Easy to put on and the cats don't seem to mind them a bit. I'll be buying them again in eight months.

    Worked quickly
    I had been using Frontline Plus, and even if with regular vacuuming, we just couldn't keep the fleas at bay. After I got these, all three cats were scratching less within hours, and by the next day, were flea free. I still occasionally spot on on them, but it never lasts long. The difference was like night and day. Still waiting to see if it lasts 8 months as claimed, but even if it only lasts half of that, it will totally be worth it.

    Had a terrible flea problem. Cats were miserable. It took about two days to notice then another 3 before I didn't find anymore fleas.

    3-pack seresto
    Great product. It is so much easier to put on these collars then to put the drops on the back of the cats necks. The product does last the full 8 months. The price is much cheaper in the long run from buying the flea medicine that is put on the necks of the cats.

    Awesome Product
    We had a flea explosion last year and nothing worked. We finally called in the exterminator. We put the Seresto collar on the dog in Sept. after we had the fleas under control. It seemed to work well for her. This spring All 5 animals are wearing the Seresto collars and so far we haven't seen any fleas. 2 are indoor/outdoor animals 1 cat, 1 dog and so far things are looking good. Lets see what happens in July and August when the real summer kicks in but I am hopeful this is going to be a good year!

    Excellent product
    We loved this the first 2 times. It was well worth the purchase price for 8 months of flea free! The third time did not work as well, but we had trouble fitting the collars correctly so they did not work well at all. I am willing to try again and make sure we get a proper fit. I was concerned that the problem may have been the fleas had become resistant to the collar, but was informed that it may have been the collar not fitting close enough to their skin. I am interested to hear if anyone else had this problem too.

    Worth the money
    These are the first flea collars that I would ever recommend. They are simply amazing and the fact that you don't have to take them off to bath you pet and that they last 8 months is wonderful. My vet said to leave them on during bathing because if you take them off repeatedly the collar will loose it's hold. It seems pricey the first time you buy them but divide that by 8 months and it's worth it. Would recommend to anyone.
