"My Panda Bear hamster, Bartok, is a little too big for the bus. Because he is too big, the water bottle just takes up room, so I don't bother putting it in there. One time, he crawled out the hole. I caught him just as he was coming out! It was funny! I usually put him in there when I clean his cage, which is once a week. He's content for the few minutes I keep him in there, and he's cute, too! He looks like he is driving a school bus!"
