As Alger didn't run it off, I suspect it is a female. After Alger left, the gray cat came onto the porch and got a snack while Alger's sister watched. She didn't try to run the new cat off, either, but I think that's probably because she doesn't like to fight. I don't know what will come of Alger's tolerance of the new cat, but I suspect it will eventually be pregnancy. Alger is Gathering a harem!
It was mild again today, but overcast, and there is apt to be another rainstorm Friday. It's beginning to look as though the summer will be as odd as spring has been. I hope we don't get a monsoon season.
