The secretary neglected your cat. She allowed your cat to sit in a wet, filthy, unsanitary cat carrier on her porch all weekend; she allowed the cat to become wet and filthy; she allowed the cat to become deadly ill and she didn't lift a finger to provide proper care (and she works in a vet's office and could have called her boss if she didn't know what to do--but what dummy doesn't know that you don't leave a cat in a cat carrier on a porch all weekend); she didn't do a darn thing to alleviate any of your cat's many hours of suffering. She's not a friend and she'll be very lucky if you don't press charges against her for cruelty to animals.
