The story on the cart is..... They were woke up from sleeping at 2 am one morning by a strange noise. They thought they had a burgler so they quietly got out of bed to see what it was.. You guessed it, it was Dusty pulling the cart around all by himself. They have to hide it at night or he will grab it and start pulling and make enough noise to wake them up. Yes, he just grabs it and pulls it around whenever he gets bored or want to do something. She can tell him, "Dusty, go get your cart" and he will go get it and start pulling to show off for company, but usually, she said, he just does it on his own. He taught himself to do this and he has done it for quite some time now. He is such a RIP!! He gives hugs, kisses, washes Daddys hair and will pose anyway you want for pictures, let you put things on him for pictures, as you have sen.
