Someone gave us a pomegranate in a pot and I put it on the back porch to see if it would live. One day when I had the catio up, I watered it and Sentinel ran--actually lept off the bed and ran--to drink the water out of the dirty lid that is catching the excess water. Because I want him to drink more water, I tried filling a baking dish with water and putting in it one of the pots I keep potting soil in. He was not at all fooled and didn't drink any of this water.
Antares still loves his heated mat. Even in the middle of the summer.
