Yeah, when I looked at the measurments of the larges compared to the jumbos, it was only about 4" inches bigger so should give Caesar some room as he doesn't seem to be much of a hider anyways. He always is instantly popping out of the hide and coming to the front whenever his cage or any cage under his is opened. The jumbos will fit Dottie as the larges are pretty small on her now. She can fit in them but its a very tight fit and most of the time 1/4 of her is poking out from under it haha.
