A major consideration for cat owners when choosing the right litter box is the size of their cats. Bigger cats would need big size cat litter boxes.  Having a litter box inside the house does not mean that the cat will be using it. The owner needs to train his or her cat on using the litter box.

This is where an extra large cat litter box becomes beneficial because it can actually simulate an open space, similar to the outside, where the cat would be comfortable in using the extra large litter box when it decides to go for a dump.

Training the pet to use jumbo litter box will be a lot easier compared to smaller and cramped cat litter box. Ideally, it should be big enough for the cat to be able to maneuver inside the box.

You may prefer to have a large cat litter box rather than multiple regular sized litter boxes. It will be cost and space efficient, right?.  However, you needs to make sure first that the cats are comfortable with having to share the same litter box with other cats
