I cannot believe this company has not been sued yet… as soon as I used it on both of my cats one had the worst reaction… lost all his fur and developed heart disease. He died last night… Now I wonder what it is going to do to my other cat. Is he going to die too? This is disgusting.. Have they any idea how much pain they have caused.. yes.. they do .. they just don’t care… bottom line money. I cannot believe you can’t trust any company now days especially for your pets, your family. They are all I have. And you KILLED my baby and now what about my other baby??? I want to cuss you so bad… He was so healthy b/f I applied that flea and tick stuff to him and to boot it didn’t get rid of any fleas… Thank you Hartz for breaking my heart and so many others..
