I have a friend who has four cats, three of which are a very large breed called Ragdoll. You know cats, they are curious creatures and they love to watch and participate in the same activities be it eating, playing or, ahem, using the cat box.
These are not only large cats, but range in age from kittens of less than a year old, to two of them over a decade of age. Not only are they large, but also 'tall'. For years they used multiple cat boxes of the largest size they could find, but none of them were large enough to enable the cats to completely get inside and not 'kick' anything outside. Finding room for mutliple boxes was also a challenge.
I happened to see the solution to the large cat box need a couple years ago and told my friend who was immediately intrigued and she and her husband quickly got their own very large Sterilite storage container to make their own version.
I apologize in advance for the less than stellar photo quality of the images to follow, but I think you can get an idea of the size of the container, how they did the openings, and other special cat considerations.
In the top image you can get an idea of the length of this huge container because it usually fits underneath a wide shelving unit's bottom shelf in their laundry room. Granted, it is heavy, but the container's edges make it easy to grip as well as making it slide easily on the vinyl floor.
- I think you can see the size of the openings at either end of the box. It's extremely necessary to cover the rough edges of those openings. Don't skip that step! Kitties have very delicate skin and rough edges could cause unneccessary tears.The openings need to be high enough to make it possible the cats can step in and so that you can get a deep enough amount of litter inside to be "diggable".
- The box has one opening at either end because if one cat is in the box and another wants in, the cat inside isn't trapped in there and they can get out. This eliminates the possibility of an arguement inside the box.
- One more important tip: Put it in your budget to replace this box once a year. Odors and a bulid up of cat urine soaking into the container make this mandatory for your cat's continued good health.
