I spent the night away last night and when I got back and went to feed my 3 male gerbils there was splatters of blood all up the side of their cage! This has never happened before and I've never seen them fight so I'm not sure if they had a fight or maybe something medical? I've had a look at all 3 and none of them look injured or have any blodd on them so I am very confused.
Anyone have any ideas what might have happened or any advise??
Thanks!
