We put the flea medication as directed, on the back of my kitty’s neck, far from her reach. She ended up scratching the Hartz product and then licked her paw, getting the product in her mouth. She then started acting really unusually. Her mouth started drooling Soooo much, she was twitching, walking strangely, jumping. We were terrified, I looked it up and low and behold, horrible reviews of this product. We gave her a bath IMMEDIATELY. So blessed and thankful we didn’t leave that terrible product on my lil baby. So blessed and happy we managed to notice and wash it off her right away. I regret not doing enough research on this product. def doing that about ANY product from now on.
