I did wonder about the size of the maze house but, at the moment, J.F. is only small (he's about 16 weeks old) - heck, I watched him go into his upstairs house via the window instead of using the door
- but pretty much the first thing he did with the maze was disappear into the front entrance and reappear out of the top onto it's roof
I couldn't find him this morning so I suspect that might be where he decided to sleep, too - I was running out of the house to work so I didn't want to risk waking him up to find him..
