Can confirm 100% Tapioca always goes to his cool hide after he eats EVERY. SINGLE. TIME.
I have no idea why and he DOES use his warm hides and hot spot! Just not after feeding day. Once he was actually IN his warm hide when I fed him. He dragged and ate his rat IN the warm hide but then 2 hours later I found him in his cool hide! This boy is on a mission. Something possesses him to be a cool dude.
