It is a great litter box for cats…
It is a great litter box for cats however we had to slowly train our 5 year old cat. Do not change the cat litter. If it is compatible then keep it with the model litter robot but if not then slowly change the litter not immediately because your cat, if picky, will not get used to it immediately. Other then that, the system works and my cat loves it after 1 month.
