It's sitting on a decorative metal garden tile just in case, you just can't see it anymore. Handle is attached to sidewall to keep from being tipped over. I tested it for a week inside first and had hoped the sides would prove a nice snuggle point for those that wanted it. With the ceramic outlet mounted to the bottom of the tin, the bottom doesn't really change temp and the sides barely get warm before the thermostat kicks it off. Being such a small bulb (40W appliance bulb) in such a large tin (popcorn vs cookie) and mounted like a lamp, the heat goes up just like any table lamp with a shade. So no worry there but sadly not much of a snuggle point.
I started the thermostat at the lowest point...99 degrees if I remember correctly, but upped it to the 125 after a couple of days while using the top as a foot warmer. A smaller waterer could maybe get by with the 99. The top of the tin gets a bit warm, but even at the 125 degree mark, I could keep my feet on it. About the time I'd think about taking them off, the thermostat would turn it off.
