So Luna and BD have been together, supervised, for most of the day (over 8 hours) now and are doing awesome. No aggression at all. No humping, no chasing (unless during bunny 500s). They have stayed by each other’s side 90% of the time. Have ate, slept, flopped, groomed, got into mischief and LOTS of binkies together. I have left both pens open and they have been in and out of each other’s no problem although they do favor the closet aka BD’s. Will post some photos of their day.
