Lol! Yeah, they are good at it. I had one that didn't eat one weeknd, becuase of shed. I checked on him and didn't lock his cage. He had started shedding so I just let him do it, and decided I would check him in a few hours to clean. Well, a few hours later, he pushed his top off, and was headed to the rat room!!

I have pet rats too, thankfully he didn't make it very far. He's in a tub now. Lol.
