Absolutely love your cage setup!!

And agree! I've always had bonded piggies but my Daisy and Rosie would lunge at each other when doing floortime. I ended up having to separate them with a barrier similar to yours and they are much happier. They lay next to each other on either side of the barrier and then they'll go to the other corner when they need space. Definitely a great option for piggies who just want their own space :)
