Of my trio, two share a cage and have a cemented bond, while the third is in a different cage yet and is working on being bonded back into the group. In the neutral area that they share (bathroom), there is no spraying or territorial pooping. There was a bit of spraying in the beginning, months ago, but it died down quick after they all learned to share the room. They are bonded in that room. Now, in the living room, there are so many territory poops! I let the two out first to run around and there often isnt too many poops around and theres never any pee spots. When i put them home and let the single bun out, he poops EVERYWHERE. He will be running, stop, sniff a random object, leave a turd, then run and repeat. When he goes home, i let the pair out again (i dont pick up the poops inbetween so they can get used to sharing the living room). Blue usually leaves anywhere from 1 to 10 poops on the second go, and Bombur often leaves anywhere from 1 to 20 poops and might leave a pee spot or two. In the beginning, it was so much worse. They would all poop, pee, and spray. We have a stain up our wall where Bombur decided he wanted to mark! But, as they become more and more bonded, the less they start leaving little marks for me to clean after
