You guys and gals might get a chuckle out of this. I bought two heaters, but can't talk myself into putting the preset one in. The one I can set myself is as big as the bowl, so had to fill it all the way. I even watched it and confirmed it turns off, lol. Had to cover it to keep him in. I left room for air, and weighed the cover down so he doesn't jump out.
Don't care if it looks goofy, it even made me laugh. But if ithelps him, then its good enough. Will revisit in the morning.
Btw, he hasn't eaten since last night
