Yup, Elvis does the same thing. It was fun to watch the progression.
First, he wouldn't go near the cage without a treat.
Then he wouldn't go in the cage unless you had one in your hand and stood next to the door.
He would eventually go halfway in, but stick his butt out and prevent any door closing.
Then he'd go in and turn around, but stick his head out until you hand him the treat.
Eventually he ran to his cage every time we picked up the treat jar.
On the off chance he beats us when he "goes to bed" (9:30pm. Out to pee then to bed. Every night), he'll sit in his cage and with his eyes he'll look at you, then the treat jar, then back to you.
We don't even close the door anymore, but he knows he got a treat when he went to his cage at night, and demands we keep the routine!
