I have my sulcata, fred! Don't know if it's fredlina or Fred but he/she ate little pebbles on Saturday and just pooped them out. I'm scared there might be compaction or damage to its little bum or intenstine. There was 2 in its poop tonight in its bath and it looked like it was struggling. (Legs were kicking) normally they are just sprawled out clearly in comfort. Are all it's food today! Give it calcium supplement and it's cage is right temp and humidity!
