“What kind don’t knock things off shelves?”

The cat breed known as “dog”.

I love cats, but my wife inherited a huge collection of original Picasso ceramics from an aunt. NO CATS ALLOWED.

Dogs.

Interestingly enough, cats prove that the world is NOT flat. If it was, the cats would have knocked everything over the edges by now.
