Many O Fallon facilities offer both, and each listing above is tagged with what it confirms: services, rates, hours, amenities like webcams or indoor/outdoor runs, and whether the state has it on a kennel-license register.

Every O Fallonlocation here is sourced from open mapping data, filtered to genuine boarding and daycare facilities — not groomers, shelters, or in-home sitters — and checked against the business's own website. When a rate or an hour isn't confirmed, the listing says “call to confirm” rather than guess, and we re-verify every month so what you read here matches what you'll find.
