How To Choose The Best Litter Box For Large cats

1.First of all, decide whether you want a covered, uncovered or top entry litter box.

2.Measurements – This is super important because there’s what we think of as a large cat breed and then there are cats that are really large like the Maine Coon and the Norwegian Forest Cat.

Large takes on a different meaning. You will need the approximate measurements of your cat (length) and the measurements of the box that is under consideration.

3.Where will the box be located? Consider the size of the room where the box will be located.

A jumbo litter box designed to fit into a corner is perfect if you are low on space but have a large cat.

If space is tight the box measurements are important. Avoid the scenario of having the box arrive only to discover that it doesn’t fit into the space you had allocated.

4.Cleaning the cat litter box. Will it be easy to scoop? Does the box have handles? Are the handles built in to the box? Built in handles are desirable in our opinion, one less thing to break.

If there are no handles will the box be easy to pick up when needed to empty the litter?

5.The age of your cat. Our cat is elderly and jumping into a box with high sides is not an option although sometimes he surprises us.

Never underestimate a determined kitty. Climbing a stairway entry is more his style as in the Petmate Litter Dome.

About Measuring – Cat? Box? location?

Yes, you do need to measure the cat and the box and the intended location of the box.

I don’t know about you, but it can be hard to visualize measurements, especially once you have read through several lists of different measurements.

My mind goes into measurements block out. I need to have a visual.

It is a quick and simple matter to measure which just takes a few minutes.

HANDY TIP: Mark out the measurements of the litter box on some newspaper or even with a stick in the sand, to get a good visual of how big the box really is or needs to be.

It is worth spending those few minutes measuring, particularly if the intended space for the box is somewhat limited, or restricted by fixtures.

Even taking the measurements into account, it is difficult to say 100% that the box will be suitable for your large cat.

The dimensions may be okay, but cats assume different positions when doing their business so there is no one size fits all.

I never believed any of that one size fits all nonsense. Just like people, cats come in lots of different sizes.

Research also suggests that bigger is better.

One of the findings from this study indicated that larger litter boxes were preferable for all size cats not just large cats.

Is Your Large Cat Also A Digger And Flinger?

If your cat is large, and a digger and flinger you will need to be thinking large box with high sides, to stop litter being flung around like a snow storm.

Just don’t be telling the cat about the flinging part. There’s no need to set off some bad habits.
