My mother purchased Hartz flee drops for our four cats from a local feed store. Within an hour of applying the product, two of our four cats were disoriented, retching, and in general very sick. One of them began to have seizures on the way to the vet’s office. These were the two indoor cats. The outdoor cats seemed to be alright.
The sick kitties got rushed to the vet where they both ended up staying overnight. The total costs were several hundred dollars.
The feed store where the product was purchased had no idea of the effects it caused and pulled the product after we told them what happened.
Both cats are still alive, healthy and happy.
*This happened a year or so ago, but I was just recently informed about this website.*
