I have 2 Guinea pigs that will fight if they can touch eachother. So they are in separate cages but their cages are right next to eachother so they can interact without fighting but, I want to put one cage stably above the other for more space but I don’t know if that will make them lonley because they won’t be able to see another guinea pig, even tho they fight if they can touch each other. Or will they be fine even if they don’t see eachother as long as they get everything they need like veggies and stuff?
