Review on 🐱 Hartz UltraGuard Plus Reflective Flea & Tick Collar: Optimal Protection for Cats & Kittens by Carmen Adams

It is waste of time and money. I bought three of these to put on my cats and they didn't do anything. They have been wearing them for over a week now and they still have fleas. I've found that some of the products I buy here don't work as well when I buy the same products at the pet store. I don't know if they sell fakes or what. I usually use frontline drops with no problems, but last time I bought them I bought them here and they did absolutely nothing either. Now I will buy all flea products at the pet store.
