I definately think there should be an emergency drill that is practiced at the vets! I mean there are fire drills nearly everywhere. We've had earthquake drills at my store. We were trained in CPR in case someone has a problem. There are protocols when someone hurts themselves. And that's at a retail store! Nothing to do with unpredictable animals! You should insist they impliment protocols and inform you of what they have done to make sure this never happens again. They definately shouldn't charge you for the visit since Maya "paid" what was owed physically!
However, looking on the funny side (if there is one!) I think Maya should have a special crime fighting cape and a superhero name! MAYA TO THE RESCUE! (whether she wanted to or not!)
