I can totally identify with the vet situation. My Mir is such a loving mommy's girl at home and turns into "Satan, the cat from hell" at the vet. She is so bad that they tranquilize her. It really works well. They use gas instead of a shot because: 1. You can't touch her to give her the shot and 2. The gas works faster, wears off faster and has no side effects. It's much less stressful for Mir, the vet and me.
