We are building an outdoor enclosure to move our sulley out there and we have always used the base to a clay pot for his water dishes. They are still big enough for him but I feel they need to be a little deeper. By the time he gets in and sloshes the water out I'm filling it multiple times a day. What do you guys use for water dishes that won't get too hot , we are in Florida and I'm afraid to use glass and him burn himself?
