Missing kitten

Please if anyone sees my kitten. Pleaseee contact me i am so devastated. His name is mittens and he is about 6-7 months. He is white/brown. And he slipped through the open door yesterday evening. I’m in sparks closer to Spanish springs and if anyone..sees or knows if someone found him please please contact me. I have attached a picture of my baby. He has no collar unfortunately was going this weekend to get one for him and I’m disappointed i didn’t go sooner. He has a brown spot by his mouth which is his unique feature. My cross streets are vista blvd and n wingfield parkway
