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

    Flumethrin* 4.5%
    Imidacloprid 10.0%
    Total 100.0%
    *Trans Z-1/trans Z-2 ratio: max 66% trans Z-1 and min 34% trans Z-2

    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.

    Great value for the convenience
    We have both Lone Star and Black-Legged deer ticks in our wooded area and I often find Lone Star ticks on my cats, especially their butts - yuck. I call them butt ticks. We do not have a flea problem here.
    We have four cats and they normally get fipronil topical type products for their tick treatment which only seem to work for 2 weeks, but I have one cat that who won't let me touch her and this collar has answered that problem where I can put her in a towel and quickly put the collar on her, release her and she's good to go for 8 months. I bought this collar from entirelypets because of the problem with fake Chinese products coming from other sellers who I shall not name. EntirelyPets sells the real McCoy and is made in Germany.
    ProsWorks for the time stated. Easy to attach to my cat. Doesn't have a smell.
    ConsThe only con I can think of is if the collar isn't tight enough on the cat, as happened with my cat who doesn't like to be handled when I quickly put it on her, that she later got her front paw hooked in the collar and was hopping around. My grumpy cat allowed me to remove her paw and I carefully tightened it up so that it was no longer loose, but allowed at least one finger space between her neck and the collar. So, that was really my fault, but just be aware of cats that don't take to collars well and monitor them to make sure they don't get it caught on their mouth or a paw - tight but not too tight.

    Best flea and tick collars ever
    I have been using this collar for my 3 cats now for 3 years. Even the vet mentioned how good it was that I used this collar. I will never use another flea treatment ever!

    Doesn't work
    I heard rave reviews about this product so I thought I would try it out. We have had our house sprayed, used other treatments, and finally settled on the collar after trying to fight fleas for the last few weeks. I'm still picking live fleas off my cat. This collar doesn't work and I'm sick I paid $50 for it.

    No more fleas for MEow
    This is the second year using Seresto for my cats. Put them on and no worries for the spring and summer and fall. Too bad Seresto don't make flea and tick collars for the human pets. Seems like I find tick (s) on me every time I come in from outside.

    Greatest Collar
    I went from pulling 2-3 ticks off of my cats every day to zero starting on the first day of the collar! If this lasts 8 months it will be the best flea tick collar ever. Far better than the drops.

    I purchased this same collar last year and WOW did it work.
    I put the collar on my pet amd in 2 days there were no fleas. I will purchase one every year for my pet.

    Much improved collar
    This collar was recommended to me by a veterinarian for my outdoor-indoor cat. He still had fleas/bites on him even with topical flea protection. Within days after putting this collar on him his skin cleared of bite scabs and I noticed he was no longer scratching. He initially did not like the collar on him (naturally) but now doesn't mind it at all. I think this is a great option for pets who go outside and need strong protection.

    I was buying these from my vet when I discovered that your price is significantly lower, plus with the auto-order, I save even more. We have a colony of feral cats that we have rescued and the lower price here really helps us to protect them.

    Great product
    Two cats who hated liquid flea repellents did not mind these collars. The collars did a great job keeping fleas off my cats and I am very happy about that. Trying to put the drops on them was impossible and dangerous (scratched), but the collars were easy. I just hope replacing the old collar is just as easy.

    Great Product
    I've had flea problems this summer due to the hot weather. Topical applications only last one month. It was a real job trying to put an application on all my cats, but with the seresto collar, all that's needed to to put the collar on the cat once in 8 months. It's a savings in the long run, with what I spent to treat the cats plus the house. I highly recommend it.

    Great product.
    I bought two flea collars for my newly adopted cats, as my vet had recommended this product. I love this product. Despite putting a topical flea product on both cats' between the shoulder blades, I was still having a problem with fleas on their faces. Since using the collars, no more fleas anywhere. I will definitely but it again in the future.

    Finally a product that works !!!!!!!
    I saw a commercial for the Seresto flea collar made by Bayer. I trust that name brand. Within in a week's time a saw a difference. What a relief for all of us. It says it lasts 8 months!! That is amazing. My cats have had the collars for a month now. This product is what I have been hoping for. Thank you Bayer and a huge thank you to Entirely Pets for selling the collars at a great price. Again I AM A VERY HAPPY CUSTOMER!!

    We have a lot of flea and tick issues in Texas. I was reluctant regarding this collar but decided to try it. I first gave all my pets a capstar and then put the collars on. My flea issues are now under control and I don't have to worry about monthly drops. Thank you thank you.

    Have my order on auto ship. Before I heard of you, I had purchased one collar May11th for a cat and it still is not here. Amazon sucks you rock.
