My corn snake is 21 years old. He has not eaten in 7-8 weeks (regular feedings had been every 2 weeks). As soon as we put him in the feed box, he dashes to climb out of it, over and over. No interest in the mice we drop in.

Then, when he's back in the cage he circles around much of the day like a maniac on caffeine. Makes a beeline for the door when it's opened.

His cage is on the cooler side - about 73F - but it's always been that way and he has a heating pad under part of the cage.

He does drink water. Yesterday we thought he was dead because buried himself partially in the bedding and was still even when we poked at him. Today he's alive and moving like a crazy snake again.

Is this snake dying? I'm not sure what to do!
