Sometimes carpet is beyond cleaning or treating. Cat Urine in most cases if it is bad it has to be cut out along with pad and treat floors then put in new patch of carpet or all new carpet! SDCR went out to home in San Diego to check carpet that had cat urine just in one corner. SDCR replaced carpet and pad and treated floors in a 3′ x 3′ area and made it look and smell great again!
