I upped the meal size this time, 3, 4 days ago, and caught mine soaking her tail and where the food was.

(There were no mites in the water when she was finished, so I am not worried.)
I would take the floor temp increase advice but would not worry too much about the soaking unless your vet advises you otherwise.
Maybe she is trying to loosen something for you to clean up later.
