Each puppy came with its own fact card, judging each puppy a 1-10 ranking on obedience, huggability, intelligence, and alertness.  Later on, the Animal Hospital series ranked the puppies on temperature, appetite, energy level, and huggability.  

At least 25 card types exist.  Card organization system created by Mike Cheesman.
