So we have 2 male gerbils, born of the same litter and have lived together for 2.5 years. Few months back they had to be separated for fighting, nothing major. Kept having a go at reconciliation, but no avail. Today they have had a real fight with blood. Separated as quick as possible both have bite injuries which have drawn blood, smoky on his arm which doesn't appear too bad. But sossy has a nasty looking bite on his cheek. Both eating and drinking ok, and they are warm. Im worried about infection, anyone dealt with this before? Needless to say reconciliation will never be tried again, which is a shame and both are now housed separately in their own cages.
