Poor little Gotham. He's been all alone since his cage mates passed on a few months ago. He is over 2 years old and has two tumors that hinder his movement somewhat. He is very snuggly and I spend time with him daily. I think he's still lonely, though. I have baby ratties that will be ready to mingle in about 3 weeks. Should I give him a new, very young cage mate? Or will it be too much? What do you think?
