Why yes! So I found myself in a similar position a few months back, I have 2 big boys (18 and 20 pounds) and while I had three boxes, they would only use one and pee on each other’s spot so it would always be wet and you know that goes. Anyway, I mulled it over for a long time because they are pricey, they have generally mixed reviews and my cats are large and in charge. Well, I was wine shopping and Costco had a really good price on the litter bot brand, it had a whole set and extras and I was like imma treat myself. The litterbox was always my chore and if I didn’t clean it out twice a day the house would absolutely stink, I tried all kinds of powders, air fresheners and it would just not help. Okay the litter bot has been an absolute game changer. Mine doesn’t separate poop/pee it just all clumps and dumps into a bottom tray. I have been using less litter (now I use a fancy clumping grass based litter because my boys are spoiled and mustn’t have clay) and as long as I keep the bottom tray under control, I don’t even think about it. I didn’t realize how much of a mental load the littlebox was until it wasn’t. It did take my younger cat a little while to adjust but now he uses it just fine. My partner read that if you stop cleaning the backup box they will eventually get grossed out into using the scary robot one, and it worked lol. They have a lot of budget ones too, and if you have 4 cats you’ll probably want at least 2, but I can’t sing enough praises about it. It’s definitely a splurchase I’m glad I indulged in. Hope that helps! 🤗✨😻😻
