Criminal case Pet shops in Grimsborough

Police Pets help you to get extra rewards. After the 

completion of a crime scene investigation, they search the scene, and based on which pet is on duty, they reward you with coins, cards,experience(XP), energy, faster star fill-ups with a higher score, orange juice or potato chips.

Currently, there are six police pet shops in Grimsborough and three pet shops in Pacific bay. The pets in the later shops are more expensive, but provide more generous bonuses and higher chances to find them.
But the main condition is that you are required to earn a certain number of gold medals to unlock a pet shop. To earn a gold medal, you must earn all five stars on every single crime scene in a case, including bonus scenes. The first case only has 15 stars, and the second case only has 30 stars. Every other case (starting from Case#3 and onward) has 45 stars. But you MUST get the bronze and silver medals first before to earn the gold medal by five-starring all crime scenes in a case.
Note: you CANNOT carry gold medals earned in Pacific Bay to satisfy gold medal requirements for pet shops in Grimsborough and vice versa—therefore gold medals earned in one city are eligible only for the gold medal requirements for the pet shops in that particular city.
