Hi guys, just signed up to this forum. Not a 100% sure how to use it but I'm giving it ago! Basically one of my guineas pigs has a cut/spot on his upper lip! I've rang the pet store I got them from but her advice wasn't too great. I got them about 2 weeks ago and as expected they've been quite domineering in there new home. (Indoor cage) they've got plenty to do as I hang pepper,carrots and apples on string from the top of the cage. Lots of tubes and toys too. So there not bored! But I'm just a bit concerned about this cut/spot. There not badly fighting but they've just been vibrating and deeply purring like they do when there trying to dominate. They have separate housing and a big communal space to fun and play, I'm just not sure how or what would of caused this cut/spot and is it something to be worried about?
