Hi. I'm new to the site so please be gentle. I have had a Herman tortoise for about a year. He will now be around 2 years old. He generally seems happy and eats well. However sometimes he spends long periods of time in one corner appearing to be trying to climb out of his tortoise table. Has anyone got any ideas why. I have a 1.2m long table with heat mat and lamp plus a UV strip light. It is all laid out as seems to be suggested in all the books i've read. He has shelter to hide under.
