Not all litter boxes are created equal. This is especially true for cats of the larger persuasion. While there are issue with certain litter boxes that can trouble all cats, larger cats are particularly plagued by certain problems.
When a larger cat visits a normal sized cat litter box it is very likely that she will not have the room to properly position herself for her business. Because of this a variety of messy and unpleasant things can occur. When eliminating solid waste the cat can miss the box entirely, the cat will then sometimes try to cover her error by scooping litter out of the box creating an even larger mess.
Male cats of a larger size can create additional mess when eliminating liquid waste. With a traditional sized litter box the cat is unable to properly position himself and will frequently get urine on the sides of the box. Since the litter can not neutralize the odour of the urine spilled in this way the box will smell badly, no matter how often the owner scoops the box.
Large cats of either sex are very likely to spill large amounts of litter when attempting to cover their waste. This causes quite a mess and is frequently tracked away from the designated litter area. Even though there are many potential problems facing larger cats when it comes to litter boxes solutions are available.
The easiest solution for larger cats is quite simply a large cat litter box. A larger box allows for a cat of either sex to more comfortably position themselves and eliminate without worry of spilling over the side or spraying the sides of the box itself.
Some litter boxes feature a requirement for the cat to jump into and out of the box due to the high walls of boxes of this style. This greatly reduces the litter tracked out of the box and thrown out of the box by the cat. This also totally eliminates the chance the cat can eliminate over the edge of the box.
No matter the solution picked for your particular cat it is important to make sure your cat can adjust to the new box slowly. It is typically a good idea to keep the old box available for a time so the cat can become acclimated to the new box before being expected to use it exclusively.
