I went out to wal-mart to purchase some Hartz products for my animals. Not knowing what I would experience. I put the drops on my two cats and 1 dog. I used the spray for the kitten. Thirty minutes after putting this on my little kitten he began having convulsions. We took him to our emergancy vet after we were told to wash him three times and wash all the other animals as well. The vet thought he might have pulled thru the ordeal but the next morning we awoke to him in pain and having several convulsions one right after the other. We had to rush him back to our vet and they are treating him but they are not sure if he will pull thru or not. He is fighting for his life at this moment. No one should have to go thru this nightmare. Our animals are our childern, whom we love very much. To watch something you love in pain from a product you thought as safe is crazy. Instead of the product saying “kills tick and fleas” it should say “kills your pets on contact”. I wonder if Hartz would treat their own animals with the product they market and swears it’s safety. I pray we can take them down one day. I sit and worry every minute and pray I don’t get a phone call telling me the worst.
