Are you looking for the best litter box for fat cats? I was. My cat is on the heavy side. She’s 19 pounds of fur.

When deciding on a litter box for your overweight cat, you have to consider how big your cat is, but also what type of floor it’ll be sitting on. You must also be willing to take the time to introduce them to their new litter boxes slowly.

Large cat breeds (or fat cats) can be very intimidating! As you know, having large cats involves satisfying their needs.

Big cats like Egyptian Mau, or American bobtail, need more space to do their business.

One of the most important things you need to do is to make sure your feline friend’s trip to the litter box goes well every time.

Your pet’s health also depends on this matter, but it will be hard for you to find out if your cat is healthy unless you pay attention to the litter box details.

The best cat litter box for big cats, with the most customer reviews, is an interesting product that will surprise you.

With its stylish look, it can blend in with any home decor.  This article will show you the best litter box for large cats, for your beloved furry friend.

Factors to Consider When Choosing the Right Litter Box for Fat Cats

When it comes to choosing a big litter box for cats, you might wonder about the criteria to follow.

Cats are different, and some of the factors you can consider when it comes to buying a box are the size, shape, depth, and other attributes.

The following are some crucial elements to consider:

1.      Height:

This is very key!

A litter box of 5 to 7 inches is excellent for most cats, especially those that aren’t sprayers or don’t kick litter out of their litter boxes.

For cats that’s are sprayers or kickers, you will need cat litter boxes with sides tall enough to prevent pee, poop, and litter from hitting the floor. Cat litter boxes with heights of around 8 to 12 inches are great for these cats. However, the entry and existing side should be low at 5 to 6 inches.

 If your cat suffers from arthritis or other mobility issues, you should go for litter boxes that the entry or the existing side is super low, around 2.5 to 3.5 inches, to provide ease of movement to your cat.

2.      The difficulty of Cleaning:

When it comes to this option, it depends on your preference. Self-cleaning litter boxes save you a lot of time and effort.

However, most of them require special expensive litter.

A daily scooping ritual with regular cat litter boxes is essential when it comes to monitoring any changes in your cat pee or poop. This can help identify any health concerns like feline lower urinary tract disease.

3.      Size:

Your cat’s size will determine the litter box size and height you select.

Go for a litter box that allows your kitty to turn around comfortably, scratch, and eliminate comfortably. 

A big litter tray for cats that are overweight is ideal.

4.      Minimal Odor:

You want to settle for a litter box that will contain as much cat poop odor as possible and not stink up the entire house.

A hooded option would be ideal.

5.     Litter tracking:

One of the things you should look out for is whether your fat cat will cause any litter tracking after using the litter box.

Get one that traps all the litter from your cat’s paws and doesn’t cause a mess on the floor.

6.     Cost of the Cat Litter Box:

Determine your budget while considering litter box solutions for large cats.

You don’t have to break your bank just to get large litter boxes for fat cats.

Conduct your research and you will easily settle for a great pick.

Large Cat Litter Box Tips

1.      Clean your cat litterbox

You should clean your cat litter box frequently.  Scoop often, and change out the litter at least twice weekly, unless you want your pet to eliminate outside.

Use anti-microbial soap and warm water when cleaning and wear gloves if possible.

Cat urine contains ammonia, and breathing it in might have adverse effects on your health.

You should also blow your nose and run tissue inside your nose once you finish cleaning.

This would save you an awkward day of getting a whiff of cat litter because the dust is still in your nose.

2.      Make Your Own Litter Box

High-sided litter boxes are excellent for large cats.

 Some tend to urinate against the walls or edges, and a litter box helps keep the waste inside.

What happens when you can’t find a box that fits your cat’s needs? You can make one that particularly meets your wants and your cat’s needs.

There are several DIY options for the cat litter box; you can opt for.

3.      Choose the Right Litter

You can decide to choose clumping or non-clumping litter waste.

Clumping litter usually is cost-efficient and saves time.

 You can also decide to go for scented or non-scented litter depending on your preference.

 Although scented litter prevents odor, it can be sensitive.

Since most litters come in small boxes, you can decide to choose something for a month and see the way your cat reacts to it.

You can then change when you enter the next month. The most expensive litter necessarily doesn’t make the best choice.

Check the areas where the cats love spending most of their time to get a clue on where you can place the litter boxes.

It would be best if you considered other factors like your cats’ personality, age, physical condition, and home layout.

Since cats love conducting their business in quiet places, areas near the washing machine, fridge, and furnace should be out of your options.

A place with low traffic, away from food and water, is undoubtedly a great idea.

 You should choose a site with sufficient light. Inside your bathroom is an incredible place, but always remember to keep the door open.

 You don’t want to put these litter boxes together as the cats would certainly see them as one.

When you want to move the litter boxes, start slowly. You can begin by moving one inch every day until you reach the desired place.

Do Cats Prefer A Covered Litter Box?

Some cats prefer covered litter boxes while others don’t.

However, most cats prefer using both litter boxes equally.

 Cats love to think inside the box as long as it’s clean.

 They also love their freedom when moving, standing, squatting, and turning inside the box.

They prefer safety over entrapped or enclosed spaces.  Most pet owners opt for a hooded litter box because of the hustle, cleaning in case litter splits outside.

A hooded box tends to keep more litter in the box and also contain odor. However, it might be perfect for people but not for cats.

 Using a large litter box, cleaning daily, and using grain clumping litter is essential to prevent the cat from eliminating outside the box.

Large cats don’t do well in enclosed litter boxes, as it limits the room to extend their tails and head over to the edge, making it uncomfortable for your cat.
