@Sherry Anfinson Go to tortoisesupply.com They sell these wonderful 30 inch flat saucer things that work great for food and water for 100 plus pound tortoises.
Thanks for the information, but it said it’s unavailableI picked up a 26" dia. Plastic Water heater tank pan at Home Depot. These work great for larger tortoises. They are 2"-3" tall making them easy to sink in ground. On those hot days the tortoises can easily climb into them for a refreshing soak as well. Hope this link works for you.
