I adopted a stray kitten about a month and a half ago, that we had found in our flower bush. He was about two months when we took him in. With in days we realized him had ear mites, so I went to WalMart and got Hartz ear mite medicine. We waited about a month to use it because of his age. We put the medicine in his ears a few times, the last being July 4. The next day he was meowing loudly, and just laying around, and not acting like his normal self. So we took him to the vet and they kept him over night. When I went to visit him on the 7th they had informed me that the ear mite medicine had poisoned him. He was just laying there staring in space and trying his hardest to meow when I spoke to him. The next morning they called to let us know that Tyler had past away. I wish more than anything that I would have done research on Hartz before I used the medicine on him. If I had my little boy would still be here.
