my cats rarely are in my sewing room for many of the reasons stated here, but my Maine coon Angie loves wool and leather. she ran off with a skein of wool sock yarn and ate a little leather/fur ball we bought for her birthday. she ate it on hers and threw it up 2 ays later on my DH birthday! my son's cat lost his wedding ring. even with moving the furniture he couldn't finde it. when he moved, he did find it lodged somewhere the cat couldn't retrieve. yeah-ya gotta love them!
