### Smarty Pear Leo's Loo Too

- Rover: No noticeable drawer smell after an 11 day absence and the app identified a cat by weight; one cat kept hissing at the cycle and avoided the box. [Source](https://www.rover.com/blog/leos-loo-too-review)
- NBC Select: Used for over six months with one cat in a New York City apartment; the drum stopped when the cat approached, and the drawer filled in about 7 to 9 days. [Source](https://www.nbcnews.com/select/shopping/automatic-litter-box-leo-too-review-rcna189883)
- The Gadgeteer: Odor was much lower than a standard box and the cat adjusted within hours; weight sensing may not work on carpet or soft floors. [Source](https://the-gadgeteer.com/2023/07/15/leos-loo-too-automatic-cat-litter-box-review-dandy-at-dealing-with-the-duty-of-doody)

- Cats.com (4.6/5): Odor control and sifting matched the Litter-Robot 4; reviewer could not test facial recognition without Whisker+ and questioned whether cameras justify the extra $100. [Source](https://cats.com/?p=112270)
- 9to5Toys: Quieter and sturdier than the Litter-Robot 4 with better odor control; bin full alert sometimes fired at about half capacity and urine was sometimes labeled as solid waste.
