13 weeks:

Martina has suddenly gone into heat. Did not pass Go, did not collect $200, just put the kids on notice that the bar was closed and went into heat. She seems to have forgotten that this is how she got into this mess in the first place.

Then she bolted out the front door between the legs of a delivery man and wouldn’t come back. I looked for her for two days and finally found her passed out on my neighbour’s front door mat, with a big orange tom sitting beside her. She was exhausted.

Her suitor is currently sitting out on the sidewalk in front of the house with a corsage and a hopeful expression on his face. She's started yowling again. Now when the kittens try to nurse she growls at them, which definitely wasn't the case before she snuck out. Slow learner, I guess. Definitely time to call the vet.
