Talk about strange bedfellows!
There was no growling on Miss Hiss's part either. Although there were no witnesses (or at least none who are speaking), MMM must have been the one to join Carl since she would never allow him to approach her.
Of course, we don't know why MMM doesn't like Carl. Maybe she had a bad experience with a black cat when she lived Out There. Maybe it was because she had bad experiences with male cats. She was 3 years old when she was rescued from the streets and she wasn't spayed until after she was rescued.
Whatever the reason, we never expected to see these two huddled up with each other. The foot of the bed is one of Mica Moo's favorite places. Probably Carl was there and she didn't want to give up her place, so after the appropriate amount of growls, she joined him.
Either way, the mom is now hoping MMM will relent and stop fussing about Carl. Perhaps with one less stressful thing in her life, she will allow her eye brows to grow in. Maybe there will be an end to all world wars, famines and hunger will be a distant memory, and Congress will balance the budget.
