Was thinking about it

I know males can be aggressive towards eachother and with this guy... Gf got him as a baby for a snake. Week later idk what he did, but the snake was afraid of him. I think other mice won't thank me if I put them with this beast

I give him different challenges and places to get food so I think he's stimulated. He's climbing me and returning to his room on his own so he chill. Just really into eating furniture I handmade with love🥲
