I had Truffles out in his ball and a few days before my Grandma brought over a vegetable tray that had small tomatoes on it. So I decided to give him a tomato. I thought he wasn't going to like it because it might be too sour or too sweet for him but he seemed to like it. So when I put him back in his cage, I put the tomato in his cage. He tried to stuff it in his pouch and take it up to his bed but when he couldn't get it stuffed, he went up his tube and while he was going up I was nice enough to move the tomato to the top of his cage for him. When he got up there, he seemed surprised to see the tomato up there.
