The stools in the cage are solid. She has some stool around her anus and some wetness, but I don't show signs of it in her cage. I just cleaned her cage last night and then this morning I noticed she was sick. She is lethargic, her eyes are half open, she feels very cold, and her breathing is very rapid. Does this sound more like a cold? She is in her bedding now sleeping, but her breathing is still very rapid. She is over a year old. What do you recommend I do to treat her?
