|Somebody just had to sign my concrete.|
That's the distinct impression of a little kitty cat's paw. We don't have any little kitty cats ourselves, but we've seen some hanging around the neighborhood. I don't mind them; they help keep the mouse population down.
I also don't mind the signature in my birdfeeder post concrete. I hope the cats just leave the birds alone and eat all the mice.
While I have your attention, let me encourage you to put out some food for the birds. I replenished all the suet feeders today, too.
And I put fresh water in the bird bath, something I do freequently each week.
We try to keep the birds fed and watered year around. Especially watered; we have a small heater for the coldest days of winter. The main birdwatcher in Rolla told me that keeping the birds watered in winter maight be more important than feeding them. It is difficult to find water that isn't frozen sometimes.
So do what you can to keep a supply of water that isn't hard as concrete on the coldest days of winter.
