My best advice is to keep feeding and never limit food. And do long soaks everyday that you can especially since your tortoise has been on a food strike. That's what will get things moving along in his gut. But both things should be done always unless you are going to brumate and I can't go into that because I don't.Thanks. How long before I should worry about him not pooping? He went three weeks without eating. He ate for a week and yesterday and today have been his first starve days. Well, semi starve days actually. Yesterday I gave him about a tablespoon of romaine smeared with mazuri and today about the same amount but with spring mix instead of mazuri. I went a little longer before limiting his food because of the three weeks without eating and because the first couple days of eating, he didnt eat that much. He "peed" yesterday. Been a few days without a soak so I'll be giving him a good one tomorrow morning.
