We put a lot of large limbs and branches in Inky's environment and she has made a nest out of sticks and leaves, just like the wild squirrels. She has been raiding the Kleenex box and stuffing them in her nest for bedding. I am wondering if that will cause any raspatory issues or other health issues. She sometimes smells musty and some are starting to degrade. She continues to add new tissue to her nest. I do not want to destroy her nest unless it will be a health issue for her as she enjoys napping in it during the day. She sleeps in her bed at night which is in a cage in the house. She does sneeze once in awhile, I think maybe from Kleenex dust. Any advice or thoughts would be much appreciated.
