Strange Catch

Strange is what we found in the garage yesterday.  It's not a mouse, it's not a vole, it's not a rat, it isn't even a gopher, but what is it?  The kitty-with-no-name is certainly proud of her conquest.  But I just wish she'd take it away and not leave it out as a trophy for me to step on...  ick!

I'd post a photo so you could submit your guesses, but that's a double ick on the Ickiness Scale. *shudder*
