A few weeks ago I purchased Hartz flea drops to use on my 2 year old beautiful white long haired cat, Cotton. I only used the drops on him one time. Right after our cat did seem to develop what seemed to be a cold with some sneezing and coughing. I never really thought much of it, we thought that she just developed a little kitty cold. He seems fine now, THANK GOD!!! I was just thinking about giving him another treatment, while I was reading our local newspaper and happened to glance at the letters to the editor. One of the letters that caught my eye was from a local person warning people not to use Hartz flea products on your pets because she did and it just killed her family cat. I am so thankful to this woman for writing this letter when she did and I happened to see it just in time before giving our family cat another treatment. She may have just saved our kitty’s life. My heart-felt thanks to the lady who wrote this letter, and my heart goes out to all of you that were not as lucky as I was. May god bless you all!!
