What happens when there are many cats roaming around the house? They need a very large litter box and a lot of care. HomerunPET presents a super hi-tech litter box that empties and fills automatically, with an anti-odour chamber and extreme modularity for easy cleaning. Furry friends seem to love it and it is certainly more convenient than having an 'open' one.
