WEll since they bonded I let Cotton and Ruby sleep together 2 nites now. They did good however Miss Ruby peed once in their house not in the litterbox. And this morning I saw she peed twice and not in the litterbox. Also I saw a doggone cecal a sticky poop smushed up in the lip of Cotton’s shelf. GRRRR..
I took the cage apart and cleaned n cleaned. I had to get a tooth pick to get that sticky poop outta there it was so smuched under that lip. I fussed the whole time. 
I am wondering if she will stop once things smell like her. She had peed all over the floor for a few days then stopped. She had also left sticky poop here n there a few times too til everything smelled like her and Cotton. I guess she was too excited to eat them. New territory and being together with Cotton were all new to her.
I was going to put her in her house at nites again and let Cotton have his all to himself. Then I am also wondering that this should stop once she gets the cage to smell lke her. I dont’ know what to do. Any ideas?
Also I see her go to her cage when I leave the xpen to the kitchen open. She can’t get in it tho cause the door is on top. I wonder if she misses it. 
Another thing they do when I leave the xpen open is go together to check out stuff then when I come and say ok now go back they look then run off together back into the living room.
