I highly recommend the BoxScoop litter box series. With the different models and openings, you can get whatever you and your pets need. As a happy customer who owns and uses all 3 models, I can confidently say that these litter boxes are a great size, very easy to use and maintain, and incredibly durable. This means my litter gets changed more often and is less of a hassle than any other box I have had. My cats took to them with no issues as well. The company's customer service is top-notch. They have listened to customer feedback and have made improvements to the product over time, which is a testament to their commitment to customer satisfaction. They have helped me with some special requests I needed as well, with no issues or complaints. They were quick, efficient, and very friendly. Between their fantastic products and unmatched customer service, I couldn't be happier with my purchase/experience and would highly recommend BoxScoop to any cat owner.
