== 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!
