Usually PDA can be a tad too much, but this a very special exception. We could watch this odd couple kiss all day. Meet Milo the Dachshund and Bonedigger the lion. The pair live at the G.W. Zoo in Oklahoma and have been best buddies since Bonedigger was born at the facility. Milo looks after the big cat, who has a bone disease that leaves him mildly crippled. Height difference is a non-issue for these friends, and the lion is happy to get on Milo's level - especially if there are smooches and a teeth-cleaning session involved.
