LEXINGTON, Ky. — Kentucky coach John Calipari thought he had seen it all, then he received fan mail from a dog.

Calipari said Friday the letter arrived complete with a paw print "signature."

The coach of the top-ranked Wildcats says the canine correspondence ranks among the most unique things he's ever received. But it was somewhat fitting as Kentucky's defense has been pretty doggone good.

The Wildcats (20-1, 6-0 Southeastern Conference) rank second in the nation in field goal percentage defense behind Wisconsin and have won all three of their conference road games so far after going 2-6 away from Rupp Arena last season.

Next up is a trip to LSU (12-8, 2-4) on Saturday.
