I am very happy I purchased Leo Loos Too litter box! It really lives up to what it says it does and has made my life much easier not having to scoop litter every day! I love the UV sterilation cleaning and the easy to use app tells me when my kitties have used it and their weights. I also love the app sends an alert when the bag is full and needs to be changed. This is the best investment I have made in years! Thanks Leos Loo Too!
