Chase was found and brought to Chicago Animal Care and Control, and the information was sent to us at Microchip Help: "We have a stray with a microchip, owner's phone number is disconnected. I did reach out via email as well."
I spoke with Maria, after finding a working phone number, and she told me her family had rehomed Chase due to family circumstances. Thankfully, these circumstances have changed, and they are able to welcome Chase back home, because the new owner didn't want him back!
Maria's husband went to pick Chase up, and he is now back home with them!
Welcome home Chase! You are a lucky boy! Your family is happy to have you back home!
