Hubby thinks it is a mouse.
Edited to add MY EVIDENCE:
When I was trapping for field mice, I often caught shrews - Short-tailed shrews and Blarina brevicauda – the only venomous mammal in the world.
Ken Catania, of Vanderbilt University, studies moles and their feeding behavior. I attended his presentation at the ISBE Conference and I was mesmerized. It was the best science talk, ever. These guys are so fast Dr. Catania has to doctor-up his high speed cameras to catch these guys in action. A mole or a shrew can attack and consume a prey (earthworms) in less than a fraction of a second. Ooh, I have to share the earthworm stuff, too, but later.
EWWWWW, it was a SHREW......where's my gun????
We were both wrong!!!!
