Mosey is an old black cat that belongs to Sarah. He also wears a red collar around his neck. Mosey and Sarah were together for as long as they could remember. On their first day at Horseland, Mosey loved it so much he decided to stay, as shown in a flashback in the episode, "Mosey". Everyone at Horseland loves Mosey because he's sweet, friendly, and funny. In that same episode, it is revealed that Mosey's hearing and sight isn't very good, which is proven when Mosey almost gets hit by a car. Later in the episode, however, Mosey does get hit by a car. Sarah is devestated and promises Mosey that he will get better. Mosey knows that he will not, though, so he leaves the barn while Sarah is asleep and dies from his injuries.
