Keith and the spacemice, prompt: bath.
“I can’t believe Shiro and Allura foisted this off on me,” Keith grumbled as he carefully filled a basin with warm water from the tap and tested it on the inside of his wrist to make sure it wasn’t too hot. The mice followed his every move, watching with great interest as he sat down on the floor and set out the Altean equivalent of baby shampoo, a couple of small brushes, and four tiny towels.
The mice crowded around, climbing on top of each other, waving their arms and squeaking in a bid to be the first. Keith squinted at them. “And I can’t believe you guys like this. The hamsters at my old foster home never enjoyed their baths.”
Platt took a running leap and cannon-balled into the basin, splashing Keith in the face. Keith sighed and picked up a brush. “Okay, fine. You’re first, you little monster.”
Platt chirruped in satisfaction and floated on his back in the warm water.
