Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Questions & Answers

66 Customer Questions


I purchased this in Dec...has anyone had it stop working after 3 months?


If I want to try a new flea treatment, how long once I remove this collar, to be able to try a new flea treatment?


Is there a rebate on the Seresto colla?


How long is the soresto collar? Does the size of the cat matter? I have 2 VERY large maine coons that I sometimes have trouble using topicals on. This would be so much easier.

Answer by MellenMar 23, 2026
I always have plenty of extra collar at the end when I apply them to our cats. You won't regret buying it.

The perfect flea collar

If you need a collar that not only prevents fleas from latching on to your pet, but also kills fleas and their larva if they touch your pet then this is the product

If you need a collar that not only prevents fleas from latching on to your pet, but also kills fleas and their larva if they touch your pet then this is the product for you. After over 1000$ in other flea products, this was the only truely effective product in preventing fleas from getting on my cats in the face of a horrible infestation. The only flea prevention collar I will be purchasing for the rest of my life.

i use this collar now instead of bravecto and other liquid chemicals on his skin. the collar is effective up to about 3 months, as ive not seen a tick on him since he is wearing it. the collar will slip a bit so i have to make sure its on tight enough but not too tight that he can slip a paw under it , and its stink free! no smell, i just check it each time he goes outside to make sure its fitting well.

I typically do not buy these collars from Chewy, but this time did. I have used these collars for 6 years and have never had an issue before now. My cat, that has regularly worn these, cannot wear the one I purchsed from Chewy without sneezing constantly and having watery eyes. So, essentially, a complete waste of money.

I had been using monthly Revolution droppers, but my cats did not like this and always tried to run away and went crazy afterwards. The collar is much easier to place on my cats and we don't have to go through something like that every month - just once every 8 months. I am assured they cannot lick this off of themselves and it doesn't bring a negative association with me.

Cat had a weird reaction

My cat seemed to have a weird reaction to the collar. She started drooling, hissing at me, meowing oddly, and looked like her eyes were irritated (blinking a lot)

My cat seemed to have a weird reaction to the collar. She started drooling, hissing at me, meowing oddly, and looked like her eyes were irritated (blinking a lot). The packaging says to avoid the eyes, which I did but it still seemed to irritate her anyway. I know friends and family who use the collar without issue, but it didn't work for my cat.

works unless the cat has a naked neck

I have a munchkin that every collar she has ever worn has rubbed the hair clean off her neck. I know the collar works but very mindful if they don't have hair, it can cause some weird interactions. My cat would start hiding and showed signs of avoidance of people and food. Took the collar back off and scrubbed her neck and she's back to her feisty old lady self.

I bought this collar for my 5 year old cat who weighs about 8 lbs. within 24 hours of being on him it caused a severe skin reaction resembling a chemical burn. I ended up having to go see the veterinarian and having to give him shots of antibiotics steroids and pain meds.

Yes I've tried everything else except this. I was intimidated by the price tag, but I'll never ever buy anything else again. We have been dealing with fleas for literal MONTHS, with no success. I regret not starting with these. Easy. Put them on and my problems are solved.

Made my main coon super sick

I have used seresto collars in my cat for the last 5 years no issues. I don’t know what changed with this collar but my cat got super sick and was acting very strange and hid for two days. 15 minutes after I took off the collar he started to act better and within a day was back to his old self.

Works very well

I've got 2 cats. One likes to go outside in the yard now and then. The other would rather not. Both wear Seresto collars that have always kept fleas and ticks off

I've got 2 cats. One likes to go outside in the yard now and then. The other would rather not. Both wear Seresto collars that have always kept fleas and ticks off of them for at least 6 months. We took care of a neighbors dog who stayed with us. Apparently he brought in fleas. The collars were 7 months old on the cats. We found some dying fleas on them, so we believe the collars worked for the cats even at 7 months. Although in earlier months we had no troubles with fleas or ticks. So we recommend Seresto collars but don't wait 8 months to replace.
