When choosing a litter box for your cat, there are a few things to consider. First, measure your cat. Next, decide what kind of litter box you want. Do you want an open or closed one? Here’s how to choose the right size–one that is comfortable enough for your cat to use regularly.

Types of litter boxes

Finding the most suitable litter box for your cat isn’t easy. Litter boxes come in all kinds of shapes and sizes. The first thing to consider is the type of litter box. Should you get an open or closed one?

Open litter boxes are the most popular type. They’re easy to clean and allow your cat to move around freely. However, some cats prefer closed litter boxes because they feel more enclosed and secure.

The size of the litter box will depend on how often you plan to clean it, the size of your cat, and your cat’s needs.

The frequency of cleaning

Your choice of litter box will depend on how much space you have in your home and how often you plan to take care of the box. If you clean it weekly, a smaller box might be fine. But if you plan to clean it daily, you’ll need a larger one.

The size of your cat

It’s essential to get a litter box that’s big enough for your cat. If the box is too small, your cat will feel cramped and uncomfortable. He might not even use it. You’ll need a litter box that’s spacious enough for your cat but not too large or too compact. A standard rectangular litter box is usually a suitable size for most cats. For smaller cats, you may want to choose a smaller box, and for larger cats, you may need a large or extra-large litter box.

Your cat’s preferences

Take your cat’s needs into consideration when you’re choosing the size of the litter box. Some cats prefer a litter box with high sides so they can bury their waste. Others feel more comfortable in a shallower box where they can see what’s going on around them. A small kitten will need a shallower box than an adult cat since it won’t be able to reach the bottom of a deep box. But a large or long-bodied cat may also need a large or extra-large litter box. Ask your vet for recommendations.

How to measure your cat and litter box

Like most cat owners, you don’t think about measuring your cat. Still, you’re more likely to get the wrong size if you just make an educated guess. The funny thing is that measuring cats to fit into litter boxes is a bit of a science.

Here are the steps to take to measure your cat:

  • Your helper should hold the tape measure at the base of your cat’s neck.
  • Hold your cat while someone runs a tape measure along its back and stop at its base.
  • Mark where the tape measure meets its tail because this is the full length of your cat.
  • Wrap the tape measure around your cat’s chest behind its front legs. This will give you an accurate measurement of its circumference. You should be able to slip two fingers under the tape measure for comfort. Mark the spot where the tape meets.

Now that you know the size of your cat, add six inches to your measurement. This will enable you to decide on the right size of the litter box. With accurate figures, you’ll be able to pick the right size of the litter box so that your cat has a comfortable place to go potty.


A little bit of preparation before you go shopping will make it easier to buy a litter box your cat will use. If you follow these steps and use the right litter box size for your cat, you can live together in harmony. While some cats can figure out how to use the litter box, others may have to be trained, especially if it’s a closed litter box with either a top opening or a front door.
