Jaws and Sandy are not rescue animals. They were acquired 16 years ago at a reptile expo in Albuquerque, NM. They were about 3" across then, and have grown to about 110-120 lbs. They can live for up to 100 years, so they will be cared for by our heirs.
These girls are extremely strong, and they can dig like bulldozers. Their fencing is hog panel sunk 8" in the ground attached to 4" posts. On warm days they spend most of their day grazing on the lawn (they are strictly vegetarians).
Their natural habitat is African desert. They tolerate cold poorly, and spend cool north Florida nights in their shed under the heat lamps.
They drink only occasionally and get most of the water they need from lettuce, kale and collards from our garden.
The grass is always greener (and longer) on the other side of the fence.
