I'm wondering about the health risks for the cats, I know there are chemicals in the hair dyes I use to dye my hair and it's better not to do it too often. I too checked into this, as I thought it was going to be about cat stories and experiences. I'll still share this. I once had the nastiest cat in the world. I got her as a hairless infant whose mother had been hit by a car, and she was the only survivor of the litter. As an infant she tore up my hands, big time, as I tried to feed her. She hissed and spit at everyone, growled whenever she ate and you couldn't touch her with a 10 foot pole.., and one day at about 2 years old she climbed in my dryer between loads, I got up to the top of the basement steps, dryer was at the bottom, and I didn't put any sneakers in the dryer, sure sounded like it, opened it up and there was China Berry in the dryer, sort of stunned. She had only been there maybe 15 seconds. I swear, her personality changed dramatically, she became the sweetest cat I ever had and lived 17 years. I do not recomend this to anyone with a nasty cat.
