The Petkit cat litter bags have been developed to make the process of automatic litter packaging as convenient as possible. Thanks to a seamless roll and a special refill ring, the bags automatically expand even if the container overflows, ensuring a tight seal every time they are used. Durability has been proven through hundreds of tests. Made from high-quality polyethylene (PE), the waste bags have undergone hundreds of laboratory tests to confirm their durability and sealing effectiveness. As a result, the bags are leak-proof and excellent at trapping odours, ensuring hygienic and convenient use. A durable and efficient solution. Each Petkit refill ring lasts for around 10 automatic packs and the container can hold a cat's waste for up to 20 days. It is a solution designed for comfort and convenience in daily use. Smart reminders and easy operation. The bags feature eye-catching graphics with a warning sign that indicates when the refill ring needs to be replaced. In addition, thanks to the NFC function, the Petkit app reminds you when the bag is running low, so you are always prepared in time. Originality and ease of use. The refill ring has a built-in anti-counterfeit label that can be scanned to confirm the authenticity of the product. The simple integrated design makes installation and bag replacement extremely quick and easy.
