OK so a few days ago we put one of our mother rats back in the breeding tub and we noticed her staying to one side when she walked. She was also flattening out her body and just making all sorts of weird contortions. We seperated her and put her in a tub by herself. She stopped doing it and seemed OK but we decided to leave her in there to see how she did. She has been acting OK and seems just fine, but I noticed that her poop is green! And I dont mean it had a greenish tint it was green like this color green. Do you guys have any idea what this could be? Should I be worried? Is there anything I can do? All help will be appreciated.
