Whitey and The Usual Suspect

Whitey is wounded.  He's not hurting, but we're not used to seeing blood on his hind leg like he got tonight.

(Scratched nose? Yes. Other wounds?  No.)

Whitey's Right Rear Paw

After getting a photograph of it at a good angle, above, we can see it is obviously a claw sized puncture wound. If I was in CSI mode, I'd get a sample and compare any foreign DNA to a certain Tuxedo.
