Please spread the word for this lost cat. Lucky was LOST on October 6, 2025 in St. Peters, MO 63376 near Roland Ln. & W. Sunnyside

Message from Owner: Lucky is my baby. I've had him since he was a kitten that was left at a campground that my friiend was staying ng for a few weeks on vacay so I immediately took him in when she was looking for someone who would keep him He's very sweet and can be afraid of people he doesn't know. He doesn't have front claws so thankfully he's quite strong when he runs out when the door opens.. he was chipped ass a kitten, but the vet was never able to see it scanned and his collar had just broke when he got out. He's always been a mama's boy and he always came back. We had just moved when this occurred and could have been chasing something and fgot turned around, but idk?!? I have a $500 reward door anyone who finds him and comes where he belongs. Just a side note. . He can say some words very clear and knows the meaning. For example if he wants to go in bat and the door is closed he'll say over and over "Oh no" until the door opens. He can say Yeah and no very clear so if you hear a cat trying to soeak he's mine.

Description: Large and white with darrk gray spots and some lighter gray

Please spread the word so we can reunite this found cat with its family! FOUND on November 24, 2025 in O'Fallon, MO 63368 near Devon and Feise

Message from Finder: This sweet baby has been coming to our hse everyday since Monday night and just sits at our back door and cries. We’ve been keeping it fed and warm at night, letting it leave in the morning but today was too cold and we kept it in the grge most of the day. We’ve taken it to see if it was chipped, it was not, and we’ve posted it everywhere but no one has claimed him. We think he is a boy but we can’t tell for sure, so it could be a girl. He’s extremely affectionate and loving towards people, but if we can’t find his owner or a soon we will have to take him to a no shelter since we sadly cannot keep him. Please spread this and help us find this poor cat’s !!!

Description: Short haired gray cat, possibly a bobtail? Greenish yellow eyes, SUPER affectionate and loves people.
