When Kate and I talked about cats, I always told her that she could only have one cat per hand because you can not pet more than two cats at once. If you have more than two cats, the cats will feel neglected. She would also be in danger of being a crazy cat lady. She said I was too controlling.
Click the triangle on the left, if you wonder what I have nightmares about.
Sixteen hands means sixteen cats. I am glad there is no medical procedure to surgically implant more hands.
