Review on 😺 Hartz UltraGuard Purple Flea & Tick Collar: 7-Month Protection for Cats and Kittens by Kristin Lane

Good. In my experience, none of the flea collars deserve a 5, but it's a strong 4. It doesn't solve the whole problem, but it greatly reduces it, and I can live with that. My cats don't get upset at all, other than that they HATE collars in general. To be honest fleas are fat like the thieves that live around me so I'm glad they do anything at all as too many collars I've bought for my dogs have had no effect or made them sick . It's a relief to have them and not have to watch my poor kitties deal with poisoning like one of my dogs did with an Ultraguard plus dog collar.
