I hope this letter finds you in good health. I'm sure you've heard what happened, assuming you're even alive. Laura's been trying to make visits during supply runs, but unfortunately many of your cats have run off. I know they mean the world to you. Laura said Mari is still hanging around, though... No wonder she's your favorite.
We agreed this would be Laura's final trip out; it's gotten too risky to venture far, and honestly... we are losing hope. I asked her to leave this letter behind, though, just in case.
Scoot. If you make it back, come see us in Welch. We live just behind the post office. We can survive this together, and... there's something important I need to tell you.
