Hi all. I’ve worked in an animal shelter the past 6 months. I have seen many animals surrendered because their owners cannot afford emergency vet care. In my short time here, I have seen 3 cats have almost deadly reactions to Hartz products. Two of these cats had non-stop seizures and the third became lethargic and drooled excessively. We were able to bathe all three cats in Dawn dish soap and save their lives. These cats were lucky. There are plenty other testimonials where the pet does not lucky. I cannot believe Hartz is still on the market.
