Missing cat

This cat is just over a year old and has been microchipped. He has been missing for 3 days now. He is tabby and white chested with Tabby legs and white socks. Tabby tail and has a black lower lip. There are 2 other cats in the house missing him as well as me. They sit out everyday waiting for him to come home. Missing him so much, he's my wee world!! Please check garages and sheds maybe my baby will come home.
