I’ve heard about people having lizards, snakes and koalas as pets, but a buffalo? Are you serious? Jim and Linda Sautner from Alberta in Canada owns the largest domestic pet in the world, a 1,600 lbs buffalo named Bailey Jr. They have raised him since he was a baby, and he is still chilling out inside their house where he always wants to cuddle or suck on Jim’s hand, and when Jim goes for a ride, Bailey Jr. loves to join.
