I have had my pair of Degus, Leonard and Sheldon, for just over a year and they are the best of friends. A couple days ago, our poor Sheldon passed away and Leonard is crushed, we've even witnessed him crying in his hut. We want to get him a new friend as soon as possible so he doesn't stay depressed, but they were extremely hard to find to begin with, I have already looked all over and no where has Degus. Is there anything I can do for him? The pet store owner I got them from said he hasn't tried it but says they might be okay with a gerbil or chinchilla cage mate as they are very similar species to the degus. Any ideas as to how I can help poor Leonard mend his heart?
