While helping out a friend of mine getting his stock car ready for the race next weekend, we discussed some of our more unusual sightings of animal life over the years.
He told me that in the very garage we were working in he observed a mouse scurrying horizontally along the back concrete block wall for about 20 feet, and about 5 feet off the floor.
To a mouse’s little claws the open spaces in the rough finish of a (presumably unpainted) concrete block might provide enough purchase to scrabble up the wall in a haphazard fashion, but I would have to imagine it would only do this under panic or extreme duress of some kind.
I’m not disagreeing with Astro because I have no facts just observations. I’ve seen mice run horizontally across a wall before…they didn’t seem to have a limit to how far they could go. Mice weigh mere ounces and have (to me) feet that seem like they could find most small cracks or imperfections in a wall. I’ve definately seen the same thing you’ve seen.
I thought this was going to be a genetic engineering thread.
Now I don’t get to use my line about how I will cease to be freaked out by the idea of spidermice when I see a spider gazing tenderly into the eyes of a mouse while smoky tenor sax music plays in the background.
‘scurrying’ tends to imply rapid movement, which in turn suggests it might not have been a mouse (I don’t think they are capable of running across a vertical surface, even a relatively rough one), but perhaps something else small, brownish and having a tail - a small gecko perhaps. OTOH, if it was moving comparatively slowly - enough for a positive ID, then mouse ID isn’t implausible.
