I have learned the hard way about 30 years ago when I was really into sewing different crafts to keep my sewing room door closed when I was not in it. I had a cat name "Jetta". She wasn't too bad when I was in there but once I left the door open. I heard a whizzing sound and thought it sounded like my machine running. Jetta was laying on the foot controller. It was always very touchy. I was on the phone and couldn't hang up fast enough. After that, I installed a screen door to my sewing room door. She could see but not come in. She also gave birth twice in my scrap baskets.
