Hi! I have a 4 month old female, and am getting a 6 month old male later this week. Their cages are not next to each other, but if she was on the edge of her enclosure, and he was on the edge of his (both have plenty of coverage and hiding places), they could technically see each other (cages are about ten feet apart). Do I still want to completely cover the side of his or hers? Thank you!
