Keeping a hedgie and a guinea pig near eachother?

Hey all! I wasnt quite sure where to put this to be honest, so move if need be.



I've had a hedgie for quite awhile now, (an one before her) but I've run into a new thing. I have a friend that is looking for someone to foster or adopt her guinea pig. My girl is currently in a two level c&c cage, the top is her area while the bottom is currently storage. I was wondering if I could possibly convert the bottom into a guinea pig cage. Obviously they wouldn't interact or share a space, but I had a few concerns just being close. The main being their smells being so close, and the other being the fact that hedgies are nocturnal and guinea pigs are diurnal. Natalia is pretty quiet at night, and seems to sleep well past our loud antics and tv on during the day, but that might change when its another animal. We've had some other pets in the same room in the past with no issues, but not this close proximity. We also keep her very clean and as smell free as possible, but obviously animals tend to smell things better than us mere humans.



Any tips or advice, or is this just asking for trouble?

(If this becomes a permanent adoption, we'll be looking to introduce a second pig, as I've heard guinea pigs get quite lonely)
