So far two of my cats (when kittens) took a running leap and nose-dived into the toilet. Their timing was impeccable, between lid being lifted and butt being seated. lol The look on all of our faces...priceless. Neither one appreciated the soapy bath either.
As for quilting: The felines took a group effort and peeled back a quilt top and shredded the batting to kingdom come. It was a quilt I was not too crazy about - they must have hated it. It never happened again with any other project.
