One of the most attractive things about this litter box is the space and privacy your feline will get each time they go. There is a large entry with a swinging door that is plastic, so even though your cat will get the secrecy they want in using this box, there is also a large amount light for them, so they don’t feel so closed in. You can lift up this door (which is attached to the top of the litter box) and have lots of space to scoop and clean.

Easy to Use Features

This large cat litter box has a carbon filter that greatly helps in reducing odors, but your cat may think it’s a toy. The filter is on the top, and is easy for your cat to snatch off and play with. They will likely eventually leave it alone but, if they don’t, it’s easily removable anyway. There’s a sturdy handle that makes for easy carrying when necessary, and the locks on the side are easy to use when you want to take the old littler out and replace it. The sides of this litter box are high in the back, so your cat won’t be able to urinate on the outside.


  • Great for larger breed cats
  • Easy to clean and assemble


  • The easy to remove carbon filter may get ripped off by playful kitties until they get used to it.

Easiest Large Litter Box to Clean

Keeping litter boxes tidy is always a task, especially if you have more than one cat at home. This Petmate Hooded Litter Pan Set with Microban is recommended for larger cats, or one or two smaller ones.

Contains Litter Well

One of the biggest problems cat owners have with litter boxes is with spilled litter. Whenever their cats have to go, they do, but end up getting litter out of the box and all over the floor around it. This can make the smell even more intrusive, and make cleanup time harder. This particular Petmate kitty litter box has high sides to avoid these constant messes.

Constructed with Microban

This handy litter box is 17 inches from top to bottom, 15 inches from side to side, and is made with Microban. There are sometimes bacteria that will set into a litter box that causes very strong odors. Microban helps it stay clean, and lessens the chances of stains building up onto the inside walls.


  • High sides and back to keep litter in
  • Wide opening for your cat to get in and out


  • There is a handle on top, but it is not recommended that you carry this litter box while full

IRIS Open Top Cat Litter Box

Best Large Open Top Litter Box

The IRIS Open Top Cat Litter Box is one of the most efficient models of its kind, and helps keep litter where it should be…inside the box!

Easy Accessibility

If you are looking for an open top cat litter box that can be easily accessed by your feline but one that also keeps litter inside and off the floor, this IRIS model is perfect. The litter shield goes over three-quarters of the way around, and is easily removable for cleaning. The compact design of this litter box also lets it fit nicely into any designated area, and the sides are high enough so that your cat won’t be able to spray (urinate) outside of where he is supposed to.

Wide Dimensions

People who have larger cats sometimes won’t get the most out of their litter boxes because their pet simply isn’t comfortable while inside of it. Cats can be very picky, and when they feel cramped there’s a chance they won’t go in the spot they are supposed to and begin to find more comfortable places around the house. That is why this particular box is made with wider dimensions at 19 inches long, 15 inches wide, and 11 ¾ inches high.


  • Protective shield keeps litter in and dirt out
  • Wide door opening for your cat’s easy access


  • May have to scrub inside walls frequently for stuck on stains

Best Large Top Entry Litter Box

Petmate’s Top Entry Litter Pan keeps litter inside, and curious dogs (who will potentially make a huge mess of the litter) out!

Great for Multi-Pet Households

If you have cats as well as dogs at home, you know that every so often your dog will get curious and start stiffing at the kitty litter. Top entry pans like this one keep them away from the litter and from causing unnecessary messes. You cat will also have plenty of room to move around on the inside with this pan’s large 20 x 15 x 15 dimensions.

Textured Lid Keeps Litter Inside

The lid on this one is made especially for your cat’s entering and leaving without taking the litter out with him. It is grated, so normal-sized litter will fall back into the pan as your feline goes in and out. The scoop attaches conveniently to the side so it’s always findable for cleanup, and the handles are built in, so you can easily grip the pan when it’s time to dump out old litter.


  • High sides and top keeps dogs out
  • Non-slip, grated lid lets litter fall back in


  • There is a chance your cat may not initially like the enclosed space if they are not used to this type of litter pan.

What to look for in a litter box for large cats

The truth is, cats are very picky about where they will urinate or poop. How much and where they go also depends on the conditions they are living in. For example, if you have more than one cat, they will always be aware that other felines in the house may have used the litter box before them. And, if your kitty feels wet spots inside of the litter box, they may or may not use it.

As a rule of thumb, whatever the number of cats is you have in the house, you should have that many litter boxes, plus one more. This is especially true if you have larger cats, because they will not be totally happy if they have to share their ‘going space’ with the other felines. They may start out okay, and it may seem like everything is fine. That is, until you come home one day and begin to find poop pellets behind furniture, curtains, and anywhere else in the house where your cat felt comfortable enough to go in peace.

Possible Medical Issues

Your cat may have some issues that are medical which may be stopping them from using their litter box. So, don’t just automatically think that they are lashing out or misbehaving on purpose. Let’s take a brief look at some of the most popular health problems that may be causing them to pee or poop in random places around your home.


How old is your kitty? Have they been getting regular checkups lately? The older your cat gets, the more susceptible they are to become incontinent, which simply means that they have less control over their constant urination in odd household places.

A Bladder Infection

These are also referred to as UTI’s, or Urinary Tract Infections. They actually feel somewhat the same way to cats as they do to humans, in that they may cause major pelvic pain as urine is held in. This pain comes from the bladder or urethra becoming inflamed, and your cat peeing is the only way they know how to relieve the discomfort. The urination itself may also be painful, depending on how serious the infection is.

Possible Bladder Stones

Male cats have a high chance of developing bladder stones, which can cause serious blockage issues that need to be taken care of ASAP. There are a few other signs of this condition other than extra wet spots all over your carpet. For example, if your cat seems to be straining more than usual when they urinate, it could be bladder stones (which are also referred to as bladder crystals). Another sign would be if they are licking themselves more than usual, which is an attempt to relieve the pain.

One of the most potent signs of stones is if you notice blood in your cat’s urine. If you do, go the vet immediately, because bladder stones that cause excessive blockage could be deadly.

Injuries or Arthritis

As with other age issues, arthritis may make it difficult for your cat to urinate properly like they used to. If something like an old injury or arthritis is very far along, even the simple lifting of their leg to pee can be a painful challenge.

Possible Emotional Issues

Most cat owners know this as common knowledge, but, if you’ve never had a kitty before, you’d be surprised how much emotions and mood have to do with them not using the litter box properly.

Marking their Territory

If you have more than one cat, then you’ve very likely had episodes of some of your felines marking their territory. You can tell if they are performing this rebellious act if they are peeing on vertical surfaces like walls or the sides of tall furniture.

Environmental Changes

Once cats get used to things being one way, sometimes spontaneous changes can be kind of stressful to them. For example, if your living room has been organized the same way for a long time, then all a sudden you moved the couch, the television, and rearranged the entire ensemble, this is a going to come as a surprise to your cat. Maybe you have in-laws staying over for a while, people the cat is simply not used to having around. Don’t be surprised that this sudden change may result in them urinating or pooping in the oddest places around your house or apartment.

Unclean Litter Box

Cats can be very picky when it comes to where they choose to poop or pee, and if the litter boxes are not maintained properly they will choose to go elsewhere. You have to develop a cleaning routine and stick to it if you want the household soiling to cease.

Litter Box Size

If you have a larger cat, then you could need a larger litter box to accommodate them. Cats are so choosy that sometimes, even if they are a smaller breed, they simply want extra room to go the bathroom. Let’s take a look at five of the best ones one the market.
