Thank you Will County Animal Control for letting Microchip Hunters help you reach Mango's family after not having any luck reaching them from the microchip information.
Microchip Hunters did some searching, and reached the father of the registered owner. He said they had rehomed Mango, and provided me the new family's information. I called and was so happy that they were looking for Mango. They made arrangements and went to pick him up!
