This morning started like any other, until i put hartz flea drops on my dog and my cat. Within an hour my kitty, who wasn’t quite 2 years old, had dropped dead. It happened so quickly i never saw any symptoms, and didn’t have a chance to react. My heart is broken. How could they sell this when it is so deadly? My furbaby was so lively, healthy and strong. And some stupid $5 product took him from me. It’s not right and it’s not fair.
