I wish that I had known what Hartz does to animals before I used the product. My cats Tucker and Bella (brother and sister) both had a few fleas. I went to walmart and bought Hartz Flea and Tick Drops. I put the product on both cats. Bella was fine but my cat tucker started to bald a little in the area in which I put the product. He was acting normal nothing unusual. Then one day he was walking into the living room and he seized and died. My friend did CPR for 10minutes. I had no clue what happened I was a wreck. Both me and Bella saw him die. She was depressed for so long because of his passing. I am heart broken. I wish that Hartz would be shut down. The loss of an animal is horrible. My house seems so much quieter now and I hate it. He was the little trouble maker and watched over his sister. I am thankful he did not die in pain it was very quick but I just wish I knew that it was preventable. For now on I am sticking to Dawn soap to treat fleas. To get rid of fleas around the house I sprinkle salt. I miss him so much and I wish that some how Hartz could realize that they are ruining families.
