VICSOM 4 Pack Flea Collar for Cats, Cat Flea and Tick Collar 8 Months Prevention Cat Flea and Tick Treatment, Waterproof Adjustable Cat Flea Collar, Natural Anti Tick and Flea Collar for Kitten, Blue

Nice flea collars. They have worked well for 8 indoor cats.

I liked the value and ability to buy all at once. For a family of multiple cats, it is a great option for clea control. And smells good too

Doesn't work. I bought 2 boxes because I'm fostering a couple cats and these collars aren't working at all.

I bought these collars, even though I was skeptical. In the past I bought another brand flea collar and it gave my cat a horrible reaction on his neck. But I wanted to try this one based on the reviews. All three cats had it on for about a week now. So far no reaction. It seems to be working, although I saw a flea on one of them. They seem to be scratching less, and their hair is growing where they were scratching. They smell good and I got 4 collars which saved money. We will see what happens as time goes by.

My cats have been doing better since I bought these for them

Doesn’t really work on my animals

Fleas don't believe in Homeopathy. You can either use real products designed for repelling fleas or you can be organic and have your cat continue to be infested with fleas.This collar is not working as designed on any of my cats.I will keep the collars on the cats for a while longer to collar train them and then get them "the real thing".

Excellent fit
