Instructions
Look at your cats and decide which one needs attention first. Pick the animal that looks the most listless and shows more symptoms of disease, such as sneezing or meowing uncontrollably.
Play the diagnosis mini-game to find out what is bothering the cat. There are six games and they are randomly chosen and include using stethoscopes and other medical devices. Finish the game to diagnose the cat.
Select the medicine suggested for the cat and administer it in a mini-game. Make sure you select cat-specific medicines, such as medicine for feline colds, or it won't be effective and the cat owner will take her cat to another veterinarian.
Take care of the cat in the post-treatment care center. Alternate between stroking and playing with the cat to bring its happiness level up. Release the cat once its happiness level is full.
Repeat the entire process with the other two cats to heal them. Make sure to pick the sickest looking and acting cat first if possible. Leave any new cats that show up to be healed after the first three cats.
