Review on Hartz UltraGuard Plus Flea and Tick Kitten and Cat Collar (Pack of 2): Superior Protection for Your Feline Friends by Dragan Nelson

DO NOT BUY FROM HARTZ. Last night my sweet kitten who is only 2 years old died a horrible, agonizing death because of these collars! He only wore it for a few days, our vet came to his rescue in his pajamas. He had blood clots all over his body, he was almost lifeless, and his gums were blackened. She rushed to his office to get started before we knew he had been captured and was dying. Our family is devastated by his avoidable death! DON'T BUY HARTZ! We will submit claims to HARTZ, SELLER and AMAZON in the HOPE THAT IT WILL NEVER GO THROUGH!
