Well, my wife was heading out to choir practice last night, when she heard some meowing. As a cat person, she realized that it was of the I'm in distress kind, not the usually I'm here, I'm here kind.
She picked up the poor little thing, and brought it inside. We isolated it in a room away from our two 'old ladies', and gave it something to eat and drink. It gobbled that down so fast I was worried it would get sick, but he then curled up in my lap, and turned on his motor.
This morning my wife called the vet, and got him in for a quick checkup. Turns out he's about 9 weeks, must have just been weaned off his mom, but we really have no clue where he came from. He's in very good shape, and has the usual ear mites and worms found in many a young kitten found in shelters nowadays. We started him on his shots, and took care of everything else. So, other than a crooked tail (which the vet said was probably a ligament sprain that happened when he was very, very young) he's our newest member of the family. The 'old ladies' know something's here, but are not exactly sure what. He'll get to know them better in a week or so.
So meet our new kitty, Luke Skywalker.
