I had an indoor 5 year old cat and somehow he got fleas. I went to the Family Dollar and purchased Sergeant’s Silver Flea/Tick treatment for Cats. I used it according to the directions. Within a few days my poor cat became sick. Not eating. Crying. Hiding. Unfortunately this happened on New Years Eve 2019. I could not find a Vet office open! My buddy, my guy, the first cat I’ve ever had DIED because of this medication! I buried him in my backyard. I’ve never had to do that to one of my pets before. It was one of the hardest thing I EVER had to do in my life! BUT it was New Year’s and I had no choice. I had always had my dogs put down at the Vet’s. I was and still am heartbroken. I so want to SUE the heck out of Hartz!!! His death was totally uncalled for!!! As I’ve read some other postings where using this product caused harm and/or death to their pets….WHY can’t we band together and sue them???????
