QUESTION! We have 2 (f) sulcata tortoises- about 65 lbs each. We've had them for about 7 yrs. They're happy,healthy, roam freely in a very big back yard, eat great and have dug a terrific deep den. No problems. They're social and happy; they'll eat out of your hand; follow us around the yard; they interact with our two large dogs with no problem and love to have their necks rubbed - very social. Two days ago a gardening crew came in, did a ton of work, and left. Since then, one of the tortoises won't come out of their den and the other is tearing up the back yard - knocking over potted plants, knocking over or tearing out succulents, dragging furniture all over and just being a terror. Why the sudden aggression??!!! Does it have anything to do with hibernation season? (though that would be a first). Was the sudden crew in the yard an overload and she's extremely agitated? We can't figure it out!
