So,
Maximus is... extremely surprising.
The first two nights I did not see him at all. He took to one of the hideouts and burrowed in well. I did see signs of him foraging and finding food, and some things were slightly shifted. I put some bedding on his wheel to make sure I would know when he found it, and both nights it was gone. Last night I heard him scratch around and dig and was well satisfied knowing he was moving around and exploring when I wasn't around.
This evening I was not expecting to see him either, but behold, as I sneak in he's right out, perking his ears and sniffing in the air. I was super excited to see him but sat quiet, only whispering to him, and he stayed and observed for a good 10 minutes before starting to groom himself. After that it was full on exploring, getting on his wheel, more grooming, racing through tunnels. I am amazed of his confidence and I completely adore his personality that is already so strongly shown.
I can't wait to get to know him further. (:
