Cat Fancy Magazine(formerly CATS MAGAZINE) has published articles about Hartz products harming cats, expecially flea soap that is used in bathing them. I believe Wal Mart and perhaps others, were forced to take the shampoo off the shelves for a time, but I think it is back in the store. I will not use anything made by that company for my cats. I only use products recommended by my vet. You may want to get in touch with the magazine to see if they will give you info. I know the articles that I read told about cats dying after they had been bathed.
