I'm not sure....maybe leave the TV on Animal Planet? I don't know how much Sully really likes Animal Planet but we leave it on all the time. I think once we're gone he enjoys the noise and the animal sounds.
Does he have a favorite few toys? What about giving him a pig's ear! Sully would be quiet for hours if we gave him one of those, LOL. Or a cow hoof but those things smell like a dirty barn to me! |
