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.

Active Ingredients: Tetrachlorvinphos 14.55%.
Remove collar from package, unroll and stretch to activate insecticide generator. As the collar begins to work, a fine white powder will appear on the surface.
Do not unroll collar until ready to use. Place the collar around the cat's neck, adjust for proper fit and buckle in place. The collar must be worn loosely to allow for growth of the cat and to permit the collar to move about the neck.
Generally, a properly fitted collar is one that, when fastened, will snugly slide over the cat's head. Leave 2 or 3 inches on the collar for extra adjustment and cut off and dispose of the extra length.

Works for us!!!!
By Ellie on Apr 17, 2020
My little kizmit is a small house cat. I have two dogs as well. They get Seresto collars. But being kitty doesn’t go out she doesn’t need the big heavy collar. And it actually works for the 7 months. We are all very happy Thanks for a quality product I can count on every time.

Maybe if you squish the flea with it
By Vicky on Apr 3, 2019
I bought the Seresto collars for my cats who hate outside but bought this for my tomgirl so I wouldn't feel bad if she lost it. I put it on her Saturday afternoon. She came in with a tick Tuesday. The tick was an inch away from the collar by the base of her ear. Seriously?! The weather was dry and warmish. No way it got wet or damaged. It's just garbage.

Came Broken
By Heather on Dec 12, 2018
I ordered 4 of these for my 4 cats. I can't review quite yet on how well they work as I just put them on last night but 1 of the 4 came completely broken so I couldn't even put it on one of my cats. Unfortunately when treating fleas all animals need to be treated simultaneously otherwise it tends to not work very well. I am hoping that it is an easy return to Chewy because other than this one collar I have been very pleased with them. As for the flea collars? Not so much.
