    • I love this thing so freaking much!
Size: 1 Pack
This is freaking amazing! My cat is an indoor outdoor cat. He has long fur on top of that. Before I found about Seresto, Iā€™ve been using advantage. Advantage is pretty expensive. Four dosages and it costed me the same price as a seresto. Whatā€™s worst it only works on fleas and not ticks. I didnā€™t know about the no tick part until this year. As the weather gets warmer, my cat stays outside longer. He came back with one or two ticks for three days straight. I never have a flea or tick problem until now. Thats when I found out that advantage doesnā€™t take care of the ticks. It also doesnā€™t help that my cat has long fur so itā€™s even harder to spot them. I tried to thoroughly check his coat everyday but Iā€™m worried that what if I miss one. Worse is what if he brings them home and gets it on the bed or something. I did a lot of digging around and see that the ones that does kill ticks are either prescribed by vets or have a relatively low ratings. Then I stumble on Seresto. I heard a lot of people didnā€™t like it because their cats have adverse reactions to it. I was worried an about the same thing but then say why not try it out. Ever since I got seresto, I have not seen a single tick! I checked the skin around his collar just in case his skin is irritated but so far, roughly 1 month inā€¦no adverse reactions. It works amazing. I put it underneath his other collar and make sure that neither one is too tight. I highly recommend this especially to cats who spend time outdoor. It gives me a lot of reassurance. Helps protect not only your cat but you as well. The price is actually not bad considering that it last 8 months. Thatā€™s half the price I would have paid had I use other treatments. I do want to say that you should monitor your cat the first few days to be sure itā€™s safe for your cat to use. While my cat was fine with it, it could be different for you. ... show more

    • Very good product.
Size: 1 Pack
I cannot recommend these more. Yes, they are expensive upfront. However, they WORK. I have used at least 2 dozen of these of the years, and will continue to do so as long as they keep functioning like they have. None of my cats have had any bad reactions to them, unlike the topical stuff. They take a couple days to start working but they eliminate any flea problems after that. They are reasonably durable, but you can get protective collars to increase that. Very recommended. ... show more

    • Ticks be gone!
Size: 1 Pack
Thankfully this does exactly what it says it does. I live in a heavily wooden area in New England and the ticks here are wild. The difference this collar makes when you put it on your cat in the spring is impressive. You got from picking off multiple ticks a day to not seeing a tick until next spring. Lasts the whole season too. Does not have a smell or greasy feel. very easy to use and effective! ... show more

    • What a Good Investment This Was. It Works!!
Size: 1 Pack
I have to admit that I was skeptical of this product and the price point. I have a semi-feral cat likes to come inside during the day. He is not totally tame and doesn't like to be messed with a lot. To flea comb him is to risk being bitten (and he doesn't hesitate to bite). He was having a flea issue in the summer. I have had poor results from topical flea medicine in the past, so thought I would try this, because I didn't want a flea infestation in my house. Wow, he stopped scratching and the fleas disappeared from his fur very quickly after getting this product. He hasn't had any skin issues with the collar, his health is robust. If I could turn back time, I wish this would have been available LONG ago, I could have GLADLY used this product on some of my cats and dogs in years gone by. ... show more

    • These collars WORK perfectly for 8 months.
Size: 1 Pack
This product works flawlessly. I've never seen a flea in the house since I started using these collars a year ago. I have 2 strictly indoor cats and 1 indoor/outdoor cat. Before I used these collars, I relied on the drops you put on the back of the cat's neck once a month. I ended up with an awful indoor flea problem. It was traumatizing for me AND the cats. I used to think these collars were expensive, but if you divide the price by the 8 months that they work, it is worth every penny. ... show more

If you know anything at all about house cats, you know theyā€™re full of tenacity, and audacity. Once your indoor cat gets a taste of the outdoors, itā€™s just about impawsible to keep them from wanting to be outside all the time! Thatā€™s what happened with my cat The Baroness Meowtilda Von Softiepaws (street name: Tilly). Tilly slipped out the back door when I opened it to let my smelly little dogs out. Of course I freaked out thinking sheā€™d run away and Iā€™d never see her again. But Tilly stayed in the back yard and came inside after a few minutes. I vowed to never let her out again. But 1) sheā€™s a cat with quintessential cat-like reflexes and is better than I am on her worst day, when Iā€™m on my best day. 2) The audacity I mentioned earlier is STRONG in her 3) she DOES NOT like to be picked up/held, or confined in any way, and I value the use of my hands. Sheā€™s never been aggressive with me, but I prefer not to make too many waves. So keeping her from slipping outside from time to time was not a job for which I am well equipped. Over time I got more comfortable with it since Tilly always stayed close to the house, and was always in the house over night. She has never been injured on her excursions. Then, we had a big problem. Remember the smelly little dogs? Well they suddenly became smelly AND itchy! And thatā€™s when I saw it. The dreaded flea infestation. The dogs are treated for fleas and ticks, so that meant the harbinger of the plague was feline, in species. Now imagine gentle reader, if Tilly is not the type of cat to allow cuddling, what are the chances sheā€™s the type of cat to allow herself to be bathed with flea soap? Nil. The answer is, nil. Several essential oils sprays, and flea combing sessions later- I had finally eradicated the infestation. Unfortunately Tilly developed some harsh looking ulcers on her skin which the vet advised was due to an allergy related to the flea bites. I felt awful, but I got her ulcers treated and cleared up quickly (thankfully, because they were shocking to look at and I doubt they were comfortable). My vet recommended the Soresto Flea and Tick Collar for several reasons. She said 1) it works, 2) itā€™s made for cats and dogs, 3) it lasts for up 8 l months. She did say ā€œitā€™s one of the pricier optionsā€¦ā€ but she swore by its effectiveness, and said it was worth it the price. Of course this had my anxiety riddled brain thinking these collars cost enough to make me have to decide between purchasing one, or paying my mortgage. Turns out the collars are about $68, and since theyā€™re supposed to last 8 months, that breaks down to about $8.50/month, or ~.28/ day! So I bought one and decided to give it a try. If it didnā€™t work, Iā€™d know for the future and I would try something else. Well, guess what? IT WORKS! There is no chemical scent to it, itā€™s made of a flexible rubber type material, and itā€™s adjustable. I thought Iā€™d have to fight with Tilly to get the collar on her (she prefers to go au naturale), but since the collar is adjustable with a lot of extra length, it was really easy to slip it on her neck and then pull it to tighten it. It helps to have a lickable treat at the ready to occupy your cat, if theyā€™re resistant to being collared. The collar even comes with little plastic reflectors you can attach which is great if your cat goes out in the evenings at all. Tilly scratched at her neck and the collar for the first day or so, but then she accepted it, and now I donā€™t think she even notices it. I havenā€™t had a single flea or tick on ANY of my Fuzz Butts since using this collar, and we are going on 3 years. If I had one request, it would be for whoever is in charge to make this an item you can set up as a subscription, and automatically get a new collar every 8 months. I know I forgot to replaces Tillyā€™s collar for about 10 months (and it still worked!), and I donā€™t want to take the chance of forgetting again. For now I have a reminder on my phone, along with the reminder to change my air filter and to test my smoke alarms. But it would be much easier if I could get a new one automatically. Other than that- 10/10 recommend and your fuzz butts and sanity will love you for it! ... show more
