Important information
Directions
How to apply the Seresto collar on your cat: 1. Remove the collar from its packaging. 2. Unroll the collar and remove the small plastic connectors from inside the collar, ensuring that no remnants remain. 3. Insert the end of the collar through the buckle and loops. 4. Adjust the collar around your cat's neck until it fits comfortably on them. 5. Two fingers should fit beneath the collar and neck to ensure it is not too tight. Any excess length of the collar beyond an inch past the loops should be cut off unless it is on a growing kitten, where some additional length may be needed for adjustment as the kitten grows. Also, make sure the collar cannot be pulled over the head. 6. Check periodically and adjust fit if necessary, especially if you have a kitten that is rapidly growing. 7. Seresto comes with three optional reflector clips that can be attached to the collar to help keep your cat visible at night. The reflector clips should be evenly distributed on the non-overlapping part of the collar.

There was a problem filtering reviews right now. Please try again later.
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 overnight. She has never been injured on her excursions.
Then, we had a big problem. Remember the smelly little dogs? Well they suddenly because smelly AND itchy! And that’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 she’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 coming 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) it’s made for cats and dogs, 3) it lasts for up 8 l months. She did say “it’s one of the pricier options…” 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 they’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 didn’t work, I’d know for the future and I would try something else.
Well, guess what? IT WORKS!
There is no chemical scent to it, it’s made of a flexible rubber type material, and it’s adjustable. I thought I’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 they’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 don’t think she even notices it. I haven’t had a single clear 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 Tilly’s collar for about 10 months (and it still worked!), and I don’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!

I bought these on Amazon instead of Chewy because they were having a deal. Fleas have been terrible this year, but I KNOW these collars work from past experiences.
First set I got arrived tampered with. All 4 were already open and each collar was cut, rendering them useless. Since I spent close to $330.00 on these I was livid. I did a return/replacement and as soon as they were picked up my new ones were instantly shipped. The replacement collars came not tampered with and are on the animals. Have already seen significant less itching in 12 hours. I have also been treating my furniture with Advantage Upholstery spray&combing each animal every night.
Thought I would make others aware though that my first order was tampered with. I'm not sure how or why. Wasn't even offered a percentage off or anything either which was kind of irritating, but with the flea issue I didn't want to wait even longer for a refund and to buy from chewy.
My 5 star review is because I know the product works, but I would rather give 3 stars based on what happened to me.

I bought them again, so I think that speaks for itself. I think you can get a bad batch. I have read reviews where people said they didn't work. If your cat goes out or you have animals that come in and out you're going to have fleas and these do not kill instantaneously. I don't know what the problem was with the people that said they don't work. Mine work fine.
