I assume the bottle of bleach in the background was used for sterilization purposes on the possum. As long as proper hygeine is shown, you would have no problem at the DOT. Zoo regulations however preclude any activities relating to "blowing into any orifice on any animal's body, or simulating the act of blowing into the orifice(s) of any animal, or(and here's the kicker)simulating the act of blowing into the orifice of any animal effigy."

That's my take on it, Spaw. At least you're not a goddam pirate.
