Fred was my companion for the past 9 years. He was a big cat with a bigger heart. He knew no stranger. We began having a flea problem in our basement which worked its way upstairs, so I gave my cats what seemed like the best flea control for the money. I only wish I had known a few weeks ago what I know now. Fred passed away this morning of an anemic reaction as I did all I could to wash the horrid flea infestation from him, the exact thing I thought I was preventing with the Hartz product I purchased. Not only did it not work, it deteriorated his health from a vivacious large cat to the point of dying from a flea infestation. I pray people realize the dangers of Hartz products before they learn through the loss of a beloved pet, as I did. I will miss you, Fred, but I swear to you I will do all I can so that your death will not be in vain.
