We have a 15 month old male gerbil - Roger. About 3 weeks ago we discovered an injury on his left cheek. It looked like some of his skin was ripped open like a flap (due to fight with cage mate or something else, we don''t know) and it was red and bleeding underneath. The skin flap fell off after a day or so, but the wound isn''t healing. In fact it seems to be bulging outward and is still red and raw. Otherwise he seems fine - eats, drinks, runs on wheel, grooms himself, sleeps with cage mate (his brother). Is it a tumor? Should he be separated from his cage mate? Is there a way to help him or should we prepare for the worst?
