i'll never forget, maybe a couple months ago while Yellow was deep into his winter fast and i had rarely seen him except for checking he was breathing: i came home after work and did my rounds, some needed cleaning, maybe 20 minutes into my rounds i see Yellow laying on one of his raised platform decoration looking right out at me. literally shocked me! i haven't seen him in months!!! i was like "OH! well hello Yellow! how are you!?" he hung out for a bit to watch me, then hid away. it was like seeing a dog walk on two legs!
to me: he knows where his hides are, and he knows where the doors are. he like his hides. he knows doors = food or person, so he generally stays away from the doors. he explores every now and then, don't get me wrong, but it's pretty darn rare, and why i even thought about moving him in the first place. like i said above: if he was as active as others, then i wouldn't even consider this an option.
