Seresto Flea & Tick Collar for Cats (3-Pack)
Description
Seresto® for cats kills and repels fleas and ticks for 8 months in an easy-to-use, odorless, non-greasy collar. With Bayer's innovative Sustained Release Technology, this revolutionary collar offers hassle-free, continuous protection from fleas and ticks.
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 solution for you to protect your cat from fleas and ticks.

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 your cat's hair and skin surface. 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. In fact, fleas and ticks are killed through mere contact (No biting required).

Useful Information

- Insert the 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 through the loop(s). Excess collar length of greater than 1 inch (2 cm) beyond the loop(s) should be cut off unless it is on a growing kitten, 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.

Customer Reviews
I chose Seresto as it kills ticks and fleas before they bite the cat, so no chance of disease transmission. Most other products make animals' blood poisonous and ticks and fleas have to bite to get poisoned and die. Biting allows the transfer of diseases. Also, I do not want poisonous chemicals in my cat's blood.
knock off that didnt have the same picture or same ingredients and did not prevent ticks!
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.
you take into account that it lasts for
8 months
Just make sure you get the collars tight enough. I made that mistake the first time around.
