Speaking of exotic pets, here's perhaps the best line about a case you'll read all day:
"Descendants of Ernest Hemingway’s six-toed cat Snowball that live at his museum home are subject to federal regulation because they substantially affect interstate commerce, a federal appeals court has ruled."
Polydactylism is a genetic condition that results in the cats having more toes than is typical. According to the Hemingway Museum, the cats "that have 4 and 5 toes can still mother or father six-toed kittens. Most cats have extra toes on their front feet and sometimes on their back feet as well."
