Bests & Worsts Reviews from Amazon

I purchased this being a cheaper alternative to frontline. I applied this as directed to my 14 yr old sons cat in the evening of 9/25/18. He was a 5 yr old cat. Within 16 hrs of the application the cat was seizing. He had a temp of 102 so inturn the poor things brain was started to cook. Within an hour of this behavior, my wife and son had to decide to let him go. I contacted the company of this issue and their response was "we have been getting many complaints of cats dying, please send us proof and we will reimburse you for the product and vet. REALLY!!!!! These money hungry !@#@$% How does that fix the issue for MANY victims?? I dont want your money!!!! I want, and many others, to remove and ban the company from Amazon, Walmart, Petsmart shelves!!!! This is murder!!
