Thanks to its sustained release technology, Seresto promises the type of protection you would expect from a topically applied medication in the package of an easy-to-use collar. Promising a full 8 months of non-greasy, odorless protection, Seresto will end the monthly headache of getting your cat to sit still when you carefully try to get that spot-on topical treatment onto their skin without making a mess.


The Seresto 8 Month Flea and Tick Collar for Cats is a scientifically formulated tick prevention collar that employs the synergistic action of two key active ingredients: Flumethrin and Imidacloprid. These ingredients work in concert to provide comprehensive protection against fleas and ticks for an extended duration of up to eight months.


Flumethrin, present at a concentration of 4.5%, is a synthetic pyrethroid insecticide known for its potent acaricidal (tick-killing) properties. It disrupts the nervous system of ticks, leading to their incapacitation and subsequent elimination. This ingredient is a robust defense against infesting ticks, preventing their attachment to the cat's fur and skin.


Imidacloprid, at a concentration of 10%, is a neonicotinoid insecticide that targets the nervous system of fleas. It effectively disrupts their neural pathways, leading to paralysis and ultimately causing the demise of existing fleas on the cat. This powerful insecticidal action helps eradicate fleas and prevent infestation development.


The collar is designed to release these active ingredients gradually, ensuring a sustained and controlled release over the cat's neck and surrounding fur. This controlled release mechanism contributes to the long-lasting efficacy of the collar, providing continuous protection against both fleas and ticks.


Furthermore, the collar is water-resistant, maintaining its effectiveness even when exposed to moisture. This feature ensures consistent protection, regardless of the cat's activities or environmental conditions.


The Seresto 8 Month Flea and Tick Collar for Cats is a water-resistant, long-lasting tick prevention collar that effectively repels fleas and kills ticks. Its innovative design, use of essential oils, and adjustable fit make it a practical and reliable solution for cat owners looking to address flea and tick problems without the hassle of other flea treatments.

Do flea and tick collars work for cats?
Answer

Flea and tick collars can effectively control and prevent flea and tick infestations in cats, but their efficacy can vary. Different flea and tick collars use different active ingredients. Common ones include imidacloprid, flumethrin, deltamethrin, and pyrethroids. Make sure to choose a collar with safe and suitable ingredients for cats. Some collars work by releasing chemicals onto the cat's fur and skin, while others emit a gas that spreads across the cat's body. The effectiveness may depend on the specific product and the concentration of the active ingredients. Flea and tick collars vary in how long they remain effective. Some provide protection for a few weeks, while others can last several months. Read the product information carefully to understand how often the collar needs to be replaced. Flea and tick collars are just one tool in the battle against these parasites. It's often recommended to use multiple methods for comprehensive protection, such as regular grooming, topical spot-on treatments, or oral medications prescribed by a veterinarian.

What is the best flea and tick collar for a cat?
Answer

The Seresto collar is widely recognized for its extended protection, offering up to eight months of defense against fleas and ticks. It contains two active ingredients, imidacloprid, and flumethrin, which work together to repel and kill these parasites. The collar is water-resistant, but proper fit and adjustment are crucial for its effectiveness. The Seresto collar is designed to provide long-lasting and continuous protection for your cat. Featuring a combination of tetrachlorvinphos, (S)-methoprene, and (Z)-phenothrin, the Hartz UltraGuard Plus collar provides protection against fleas, ticks, flea eggs, and flea larvae. The collar is designed to last for up to seven months, making it a convenient option for long-term control. Additionally, it includes a reflective strip for increased visibility, which can be useful for outdoor cats. The Adams Plus collar contains tetrachlorvinphos and (S)-methoprene, offering a dual-action approach to flea and tick control. It kills existing fleas and ticks and prevents the development of flea eggs and larvae. This collar provides protection for up to seven months, making it suitable for those looking for an extended control solution. It is designed to both kill and repel fleas and ticks effectively. The Sentry PurrScriptions collar is formulated with tetrachlorvinphos and (S)-methoprene, providing a comprehensive flea and tick control solution. This collar is designed to kill and repel fleas, ticks, flea eggs, and larvae. With a protection duration of up to seven months, it offers a long-lasting solution for cat owners seeking continuous flea and tick prevention.

How long should a cat wear a flea and tick collar?
Answer

The duration for which a cat should wear a flea and tick collar can vary depending on the specific product and its instructions. Different flea collars have different recommended durations of use, so it's crucial to follow the manufacturer's guidelines provided with the collar. Some flea collars are designed for short-term use, like a few weeks. These collars may be suitable for specific situations, such as preventing fleas during peak seasons or providing temporary relief. Other flea collars, like the Seresto collar or Adams collar, are formulated for long-term use and can provide protection for several months, often up to six to eight months. These collars release the active ingredients gradually over time.

What kills ticks on cats?
Answer

Several products and methods are effective at killing ticks on cats. Topical spot-on treatments, such as those containing fipronil or selamectin, are applied directly to the cat's skin, usually between the shoulder blades. These treatments can kill ticks and provide ongoing protection. Oral medications, such as those containing isoxazolines (e.g., fluralaner, afoxolaner), are administered orally. These medications target ticks and are effective for a specified period after ingestion. Tick collars, like Seresto or Adams collars, are designed to kill and repel ticks. These collars typically contain specific active ingredients, such as flumethrin and imidacloprid, and provide prolonged protection. Medicated tick shampoos and dips can be used to kill ticks on contact. However, their effectiveness may be limited to the time of application, and they may not provide long-term protection. Some cat owners may explore natural remedies, such as essential oils like neem or cedar oil. However, it's essential to use caution with natural products, as not all are safe for cats, and their effectiveness can vary.

What are the side effects of flea collars on cats?
Answer

While flea collars for cats can be effective in controlling and preventing flea infestations, they may also have side effects, and individual cats can react differently to the chemicals used in these collars. Cats can be allergic to certain chemicals found in flea collars. Allergic reactions may manifest as itching, excessive scratching, or behavioral changes. Some cats may develop skin irritation or redness around the collar area. This can be due to sensitivity to the collar material or the active ingredients. In some cases, cats may exhibit signs of gastrointestinal upset, such as vomiting or increased salivation, as a reaction to the chemicals in the collar. Your cat might become unusually lethargic or anxious or exhibit any behavioral changes after wearing a flea collar. In rare cases, some cats may experience respiratory issues, especially if they are sensitive to the chemicals emitted by the collar. Signs may include coughing or difficulty breathing. Cats may develop eye irritation if they come into contact with the collar material or if they rub their faces against the collar. Watery eyes, redness, or discharge may be signs of eye irritation. Seek immediate veterinary attention if you observe these symptoms.

Allergic Reaction
VERIFIED PURCHASER

After using this brand item on our dogs we opted to try for our senior cat. However, it was very traumatic for him as the collar "burned" his skin and left a ring around his neck hairless and with open lesions that took over 2 weeks to heal. Be very careful to observe on pets. Any indication of reaction and remove immediately. Unfortunately for us, our cat is an outdoor cat and we did not notice the severity until all hair was missing under the collar.

Love, love, love this collar!

We have always had severe problems with fleas in our house. We were using Frontline for years, but I had heard it did weird things to cats with seizures and other neurological problems, especially older cats, and while my oldest cat was always a little loopy, he did start developing things like rocking and nervous tics after using Frontline. I'm not sure it was entirely related, but maybe. Anyway, Frontline always left residue on my couches, bed, etc., so it made me nervous to have it around where anyone could sit in it, etc. Needless to say, once I got pregnant, we abandoned Frontline in the fear of my contact with it and, later, the baby getting it on him or into his mouth. Seresto had *just* come out at that time, so we hadn't yet heard of it, as it was in between our vet visits. We figured that we hadn't seen fleas in a while, so we'd be okay just going without and using some diatomaceous earth, since that was supposed to be safer. Man, were we wrong. Talk about a flea infestation! Perhaps the worst one my household had experienced yet. And what's even worse on top of that - one of my cats is terribly allergic to fleas and tears out his hair, which puts our cat allergies and related asthma to a level of 10 out of 10 in terms of misery. Simply put, our entire house is miserable when fleas are around. Once the vet saw how covered in fleas one of my cats was, she recommended Seresto, and we haven't looked back. Talk about fantastic! It really does work for the full eight months and, to be honest, I've forgotten the exact date sometimes and gotten the collars late, and we *still* don't see fleas! Haven't seen a flea in the house in nearly four years, and we are constantly going in and out, and now have dogs (who also wear Seresto collars). I'm still a little worried about potential carcinogens, even though the website says they're safe, but the short-term relief we all feel from these collars, along with the lack of residue, is worth their weight in gold. Seresto collars have saved my family an immense amount of misery and have become an invaluable source of flea control in our home.

Seresto Collars
VERIFIED PURCHASER

I have 10 barn (porch) cat ranging in age from juveniles to mature cats. I used on all of them for the past summer and collars work GREAT. They stayed on as they roamed the 20 acres and beyond with no issues. I never saw a tick or a flea the entire 8 months...on them anyway. BEST PRODUCT FOR US!! It's hard to spend the money, but in the long run I have peace of mind that my babies are covered. We live in highly wooded area where ticks, fleas, and other things are VERY present and none of our animals seemed to be effected. I saw some reviews of allergy breakouts but none of mine had any issues.

I am leaving a review of the Seresto Flea and tick collar. It's a bit of gamble really, the first time I used these collars for both of my cats - they seemed to work really well, maybe the second time also. I ordered them again and have found that they are not so effective this time around, not sure if the fleas get used to them or why they seem less effective but, will try it for the fourth round. I also do not think they last anywhere near 8 months, I have been changing them out every 5 to 6 months.
