Added point of information I have added the following A house cat typically weighs about 8 to 10 pounds 3 6 4 5 kg 19 while as of 1957 a slice of bread weighs only about two thirds ounce and a pat of butter about one fourth ounce 20 Therefore attaching a buttered piece of bread to a cat would have a negligible effect on the movement of the much larger cat I believe that this observation is appropriate for the tenor of the article as a whole Cheers
