My box turtle is about 14 years old and we take pride in how long he has lived so far. But recently, after I cleaned his cage which is situated at a big bay window in my house, I came to his cage to feed him and he started running towards me and whenever he sees someone now he always tries to get out of his cage. He never started doing that before that one day and now he keeps doing it! Is he okay? Also, I took him outside for a while as I usually do to see if that would help and it didn't. Any suggestions?
