Katziela Washing Machine Cleaner Tablets Formulated for Pet Owners 24 Pack (1 Year Supply). Pet laundry is tough—fur clings to fabrics, odors linger in your washer, and regular cleaners just don’t cut it. That’s why Katziela Washing Machine Cleaner Tablets were created specifically for pet owners who want a truly fresh, hassle-free clean. Each tablet is powered by a plant-based, enzyme-rich formula that helps break down the residue, grime, and strong odors left behind by muddy paws, drool-covered towels, and fur-lined bedding. Unlike ordinary washer cleaners, our formula is fragrance-free, so it eliminates odors without covering them up with heavy scents.
