What U. S president kept two crocodiles as pets

Well, in the first place, they weren't actually crocodiles but alligators. The difference of the two would be that crocodiles are more on the seawater and alligators favor the freshwater. They also have a difference in their head shape where crocodiles are much more like a V-shape rather than the alligators that usually have a U-shape look. Their appearance would also be an indicator since crocodiles are lighter in color where alligators are darker. The US president that kept two alligators as pets would be the 31st president of the United States which is Herbert Clark Hoover.
