For cat lovers unsure if their cat will take to our products, we offer a 30-day trial. The trial starts from the day the package is delivered. You must first contact customer service before returning the product to receive a refund. Rather than return the item to us, we prefer used items are donated to local cat shelters and rescues. Money-back guarantee only applies to items ordered on TheRefinedFeline.com and not purchased through 3rd parties. Please contact those retailers regarding their return policies.
