Got a call from the vet. So far everything is negative so the true cause is still a mystery. One test left and wont hear back till tomorrow. Getting a stool sample yesterday was easy. when the vet restrained her to check her out she let go of everything else she had. No sign of blood in it or in her cage this morning. She is hiding still digesting her meal from Sunday. Have a second visit tomorrow at 5 with the vet. Spending mad $$ but she is worth it.
