Update from the household at 5:30AM.
Husband maneuvered litter box into a position that Batman favors. No more shitting/peeing in tub thus far.
Alone all day yesterday, Batman seems to be bored and restless. Last night, he basically roved around. Knocked a glass of water off of the night stand. Husband jumped up panicking.
We got up to eat breakfast. All very sleepy.
Attempting not to strangle Batman.
