This one made me laugh.
You mean that having a cat's paw under the needle, a whole cat on the blocks to be pressed, and kitty supervision while cutting is detrimental?
Naw - can't be.
Kitty holding down the stack of fabric - marking as much of it as possible with hair - doing the maximum stretch when trying to lay something out. Rearranging the blocks laid out on the floor or table. Gotta admit - sometimes they are cute!
