We currently have a litter robot 3. We’ve had it for 4 years and love it! We’ve had to replace a few things along the way but love that we can buy replacement pieces. We have two cats and are contemplating getting one or two kittens this summer. I read the LR3 can hold up to four cats. I saw the LR4 and LR5 can hold up to 5 cats. Would it be better to upgrade? We don’t want to put too much strain on our current model.
