Sleeping more than usual?

[Jude curran]

Over tha past week or so i have noticed that terry. (My 2 year old russian) has been eating all of his food but he is sleeping alot. My heating is correct and his enclosure is 5 feet by 2 and a half feet. He is 4 inches long. I wasmt sure why he was sleeping so much and i am rather worried.

Any help is much appreciated
