Looking to rehome my lonely boy, Andy (Chicago area)

My girl has passed away (she was in the cage next to him), and I think my boy is lonely now. His name is Andy. He is 12 years old and seems to be in excellent health. He eats Oxbow pellets, hay from Kleenmama's, and gets organic apple twigs daily. He's in a double Critter Nation, so he is quite comfortable, but I do feel sorry for him being all alone.

If anyone here would be willing to take him so he could have a buddy or two, I think he would really love that. I love Andy, but I want the best for him and don't want him to be lonely :(
