Lost Cat, Need Help - Fed Hill

Hi all. My indoor cat, Leo, is nowhere to be found inside my house, and my roommates and I have torn apart the house several times and nowhere to be found. We are assuming he must have somehow got outside, and we can’t find him. I am checking all the shelters and putting up flyers ASAP tomorrow. If anyone sees him, please let me know. Our house is in Fed Hill near the Bmore Licks/a few blocks from the park
