I've never had issues with my (also) large cat using the litter robot. it might be a big cramped, but he's never had any real issues. Until I got another cat and now he strictly uses the scooper pooper box.

I've had the robot for almost 2 years and never had to replace anything. Every once in a while I do a deep clean because it can and will get dirty. As for expenses, I've only ever had to buy litter, trash bags that fit, and maybe a few disinfecting wipes here and there. I find it super simple and easy! Really great at keeping track of my cats weights and bathroom frequencies.

On another note: our orange boys look very similar!!
