Hello everyone, I just adopted a 9 year old Sulcata. The previous owner has fed him nothing but rabbit food and spinach. He did graze in the summer.. according to her. I got him home, Soaked him immediately cause of how dirty he was. I used the brush on his shell and cleaned him up. He is a beautiful tortoise. His shell is pyramided VERY BAD.. He has what looks like growth cracks in his shell. I was rubbing his shell and saw some dirt in the crack.. I used the tip of my finger nail to get it, and he jumped and ran.. and when I say ran.. I mean RAN.. I feel bad and I think I hurt him. The previous owner also never had water for him. I have been feeding him orchard mix with Romaine and Calcium powder cause he has had close to no calcium for the past 9 years. His back slants in from lack of calcium. What are the cracks that when I touch he jumps and freaks out and runs? Any ideas? thank you.
