I purchased this product on Wayfair. I like it for the most part. The biggest issue that I have with it is that the detected weights are nowhere near accurate for my cats and my cat's weight "changes" drastically every time they use the litter box. For example, if one of my cats uses the litterbox three times in one day, their weight might go from 7.8lb the first time, 5.4lb the second time, and 8.2lb the third time. In my opinion, this defeats the entire purpose of tracking weights because it can never detect which cat is in the litterbox. Might as well get rid of the app at that point. I wish there was a solution to this because I like the litterbox aside from that.
