yep a box with holes punched in the sides and flaps to close so she doesn't get traumatized in the office by dogs, cats etc. I think most vets have the boxes that cats can be transported in you might be able to get one of those they have handles for easy carrying. They use to be fairly inexpensive too.I think even a box would be a good idea. The car with just you is one thing, what about at the office where there could be other animals and people. If nothing else, I would grab a pillowcase to slip her into while in the waiting room. think what being around strange dogs will do to her.
