I recently had the scariest experience and felt the need to share in hopes it can help someone else. I gave my cat 'Hartz UltraGaurd Topical Flea & Tick Prevention for cats and kittens' and it was the worst decision I've made. I bought the medication at Walmart, but it can be found at many retail stores.
Minutes after I applied the topical flea medicine to my cat's neck, my sweet Dory started acting extremely weird and aggressive, which is so abnormal. I started to watch her closely and then noticed she could barely breathe, her heart was racing, she couldn't open her eyes, and she was foaming at the mouth.
The relations my cat had happened within 10 minutes of the treatment being applied. I can't imagine what would have happened if I were to of left for class or happened to just not of been home to know what was going on. Fortunately, my cat is so lucky I was home and able to get the product off of her as soon as I noticed these deathly reactions.
I have read almost 100 reviews of people tragically losing their pets from Hartz products. I am shocked that so many people have had such negative experiences with this brand, yet their products remain on the shelf.
DO NOT BUY ANYTHING FROM HARTZ.
I have included the link to a website I found that was made specifically for people to share their stories about their pets death, or near death, because of this brands products!
