So Teo checked out ok. He no longer has an RI. Has been burying himself completely on and off most nights, and then he also tends to sleep in his house now. The last few nights I have not been using the CHE to check how he does. He seems to be doing fine, will move into his house a few minutes before lights out, or will start digging. I am so happy with how he is doing. He's eating well still, though he has definitely slowed down. Need to weigh him again.
