Eak! So glad you're feeling better. I purchased some kitty flannel years ago but I didn't remember from where because it was a while before I went to use it. I washed it but there was a petroleum type smell that would not go away. I washed it several more times & then threw it out as I couldn't get rid of that smell. Luckily, I didn't have any reaction but I didn't want anyone else to end up with it either. I never had anything like that happen since and that was probably close to 10 years ago.
