Study of animal urination could lead to better-engineered products

Sir Isaac Newton probably wasn’t thinking about how animals urinate when he was developing his laws of gravity. But they are connected – by the urethra, to be specific.

A new Georgia Institute of Technology study investigated how quickly 32 animals urinate. It turns out that it’s all about the same. Even though an elephant’s bladder is 3,600 times larger than a cat’s (18 liters vs. 5 milliliters), both animals relieve themselves in about 20 seconds. In fact, all animals that weigh more than 3 kilograms (6.6 pounds) urinate in that same time span.
