Casa Leo Leo's Loo Too: What to Know
Leo's Loo Too is made by Casa Leo, the company formerly named Smarty Pear; Casa Leo's own site confirms "Smarty Pear is now Casa Leo," and this Amazon listing is still sold under the legacy "Smarty Pear" storefront name, which is worth knowing so it doesn't get mistaken for a discontinued predecessor product. The box uses an automatic sifting drum with a 9.5-liter sealed waste drawer, which Casa Leo describes as among the largest capacities in the category, and it's rated to accommodate cats as light as roughly 1 lb up to 20 lbs.
The standout feature is Casa Leo's EPA-registered UV odor and bacteria treatment, which activates inside the sealed drawer after each use, intermittently through the day, and on demand from the app, layered on top of bamboo carbon filters. Safety hardware includes a radar-based motion system, four separate weight sensors, and an anti-pinch sensor, and Casa Leo rates the unit at roughly 30 decibels, the quietest stated noise rating of any box in this guide, though we could not independently verify decibel testing ourselves.
We picked this specific bundle ASIN, which includes the litter box, carbon filters, waste bags, and a litter mat, rather than a bare-unit listing, since Leo's Loo Too is sold under several different Amazon bundle configurations. At $599 at the time of our check, it lands in the same price range as the Litter-Robot EVO. The app supports iOS and Android and adds Alexa and Google Assistant voice control, which none of the other four boxes in this guide offer.
