• Sleep on their front rather than their side to
make a quick escape when threatened

5. Do they Sleep Uphill?
• Bighorn sheep in the wild sleep with their
heads uphill for better perspective for
approaching predators around and below
them, and falling rocks warn them from
predators above.
• Predisposed to Vaginal prolapse due to
increased strain from gravity when they sleep
uphill.
