I think Jesse may be going deaf with age. For the last few weeks or so, he hasn't been responding sounds much. I can tap on his cage and yell at him and he just keeps sleeping and when he's awake I can reach in and give him food and unless he's facing me, he has no clue I'm even there. Poor little guy is so ancient. He looks old and scruffy. He even shakes when he walks sometimes. When I look at him I get images of a little old hammy with a long beard and a little walking stick. It's gotten to the point where I'm checking on him several times a day to make sure he's still here. He always is. I just sit and watch him wander around his cage eating, drinking, sleeping, and running in his wheel, and treasure every second of it. I'm really going to miss him when he finally does leave me. He is such a great little hammy.
