Gerbil trouble -Need urgent help!?

Sorry, but theres not much you can do. I wouldnt try buying a new gerbil because it is likely he will fight with the new one. The best thing to do is to just wait it out with Squishy. Since he is old it shouldnt be long before he'll p on with Elvis. I would give Squishy some treats and hold him more and play with him more so he wont be too lonely. Elvis might of been his friend, but Squishy has another. YOU! ♥
