This evening she started her mate-calling again. Both months she has done it away from me in my walk-in closet. The timbre was different from any other sound that she had then made. The sound was part of the constellation of new behaviors that led me to take her to the emergency veterinarian in the middle of the night on Feb. 13–and learn that he was a SHE and was in HEAT. Every member of my family has advised me repeatedly to get her spayed. I don’t remember if the emergency vet told me that as well.
