The original KENNEL KARE! This product has been tested and EPA approved to kill the parvovirus, Panleukopenia, Calicivirus and other highly contagious, potentially deadly viruses. Not only is this product effective but also very user friendly and safe. No more risk of harmful gasses, unsafe environments for people, animals or damaged enclosures and facilities. KENNEL KARE is a stable product with a prolonged shelf life, meaning it wont start to lose its efficacy the instant it is mixed with water like other parvocidal products available on the market. There is good reason why KENNEL KARE is the preferred and trusted product in so many animal care facilities across the country!
