Ferrets Sleep the Day Away

Black-footed ferrets sleep up to 21 hours a day, and mostly hunt during the night. They mainly prey on prairie dogs, hunting them in burrows and taking their shelter. Due to a government-assisted wipeout of prairie dog towns in the 20th century (because their underground burrows are destructive to farmers' fields), the black-footed ferret also suffered from lack of food and shelter. As a result, the animal is still endangered.
