Review on 🐱 Hartz Ultra Guard Flea & Tick Collar for Cats and Kittens - 2 Pack by Tony Crook

I have 3 cats, these collars didn't fit us. We bought them a few weeks ago. We used to use collars. One of our cats ***really*** didn't like the collar. The collars have a strong odor and he didn't have one. We had a hard time keeping him. One day there were evil looks. After a day or two the smell has diminished and our cat seems to have forgotten it was there. Within a few weeks, the fleas seemed to multiply and get worse. The cat's heads were covered with fleas and bites, even under the collar. Fleas have been implicated even among us humans. Earlier this week we (collars removed) bathed cats, bought and used a different type of flea control.
