My old border collie would invent games and play them by herself if she was left to her own devices. Other breeds (and even others of the same breed) not so much. It makes me wonder if the ability experience boredom, and to undertake activities to alleviate boredom, is part and parcel of higher level intelligence. Most lower animals don't have sufficient time aside from basic survival activities to allow it?
