i couldnt find my cat anywhere one day (if found text me)

so i have this cat named Looke and he has been a indoor for about a year now and one day i didnt see him anywhere normally he is the most easiest cat to find at my house so i was wondering where would he have been so i asked my mom and we looked everywhere all around the house even at the spots that we barely check so we checked outside didnt find him since we live in the middle of nowhere we have cornfields and i gosh i hate them so i was hoping he didnt go their so i was worrying so much at school and my parents were looking everywhere so i told them bring his litterbox outside and the last time i was with him was i was holding him and singing then i put him down and went to school so far we know our screen door can open very easily and there might have been a thunderstorm i dont know ca
