The way I understand it is that the tag is a cites tag from the feds and has to do with endangered or restricted species and since the bobcat pelt looks like some other endangered or threatened species they tag it if you plan to keep it, mount it or sell the fur to document that it is not an endangered or restricted species if it gets checked somewhere down the line. That's the way it was explained to me, and the dcnr doesn't want to waste time or resources tagging animals that aren't kept.
