I'm really worried about Marigoldy tonight...she sounds so pitiful & pacing, pacing, pacing. She keeps going to the door like she wants out, but it is so dreadfully cold that I don't want her to go out. She meyowls and meyowls so loud, we can hear it upstairs at the other end of the house. I get so upset when she is like this...because she doesn't act/sound like a happy kitty. It's so mournful. This is the third or fourth time that she has gone into "heat" since we got her, and everytime it seems to get worse & worse. I'm so sad...
