Because the WindClan lands are mostly comprised of moors, many horses roam in this area. They are owned and were raised by Twolegs, who created shelters in the ones they reside. Their horses live on a stretched barn where they are constantly trained by the humans. Its not a very safe place for the WindClanners to meander by, for horses run at very high speeds and can callously crash any creature below their feet, including cats. Because its a barn, its bursting with mice, tempting many WindClanners to risk their lives and go for it. Literally. The WindClanners are passive by nature, and are wise enough to not stroll in these boundaries. Only those who have, have done it at night, when all the horses and Twolegs are asleep. It's a serene atmosphere, that unfortunately doesn't last long, for Twolegs wake up early the next morning.
