In the end our cat didn't survive her fall. She died Friday evening. She was doing well until four or five days ago. However, when we woke up about five days ago, she wasn't getting up, not walking around, not eating, hardly drinking water. We still don't have a clue as to what might have happened, neither does the vet. By Thursday, she seemed to improve a bit. Friday evening though, while I was reading my email and she was lying underneath the desk at my feet, she suddenly started breathing heavily and next thing I knew, she had died. We'll miss Yin-Yang, she was a kind, smart little lady.
