In June of 2003, I purchased a Hartz spray for birds that was marketed as a soothing gentle bath for keeping their feathers clean. I used it once and I noticed the cockatiel got very still after- but I mistakenly used it again. The second time I sprayed her, her entire body went rigid and her head dropped. She would not respond to touch or to sound. I rushed her to U of Pennsylvania’s emergency veterinary clinic where they diagnosed her as reacting with a neurological episode. They did not have an antidote. She survived- but was in that state for aproximately 2 hours.
