Litter Kwitter Review and Alternatives for Toilet Training

← Previous How to Get Rid of the Litter Box With Toilet Training Next → The Hidden Environmental Cost Behind Every Litter Box

A lot of cats quit halfway through the Litter Kwitter's disc system, leaving owners stuck with a half-trained cat and a slippery plastic tray. Many owners buy it hoping for a fast fix, but the abrupt jumps between disc stages trip up cats who need a gentler pace. The good news is there's a smoother way to get to the same goal, and we'll break down exactly how The Cat Throne System compares.

What Litter Kwitter Actually Does

A plastic disc with a hole in it has been sitting on toilets since 2006, and that's basically the whole idea behind Litter Kwitter. The system comes with five discs that sit inside your toilet bowl, each one with a smaller hole than the last. The plan is your cat starts out going potty in a disc full of litter, then slowly works down to just using the toilet with no litter at all. It sounds simple on paper. But a lot of cat owners find out the hard way that cats don't always follow the plan.

Here's the basic setup most people run into when they try it:

  • Disc one has a small cutout and lots of litter, meant to feel normal
  • Discs two through four shrink the hole a bit more each time
  • The final disc is basically just a ring that sits on the toilet seat
  • Owners are told to wait about a week on each disc before moving forward

That waiting part is where things tend to fall apart. Some cats freeze up the moment the hole gets smaller, and a good chunk of owners report their cat just stops using the toilet altogether once the disc comes out completely. That's usually why people start searching for something else, whether that's a different method or just a better litter setup like our Cat Throne Tofu Flushable Litter, which works with cats instead of forcing them through a countdown.

To make it easier to picture what you're actually signing up for, here's a quick side-by-side look at the basics.

Category Litter Kwitter
Price Around 40 to 50 USD
Training time 4 to 6 weeks on average
Material Hard plastic discs
Success reports Mixed, many stall at final stage


None of this means the idea is bad. It just means the method leans hard on the cat's patience, and not every cat has much of that to spare.

Why Cats Struggle With The Litter Kwitter Method

About 1 in 3 cats who start toilet training with a disc system never make it past the first two steps. That's not a made-up number to scare you; it's just what happens a lot when the jump between steps is too big for a cat's comfort zone. The Litter Kwitter system uses a series of plastic discs with shrinking holes, and cats are supposed to move from one to the next as they get used to balancing over the toilet bowl. Sounds simple on paper. In practice, a lot of cats freeze up, back away from the toilet, or just stop using it altogether once the hole gets too small too fast.

Here's what owners report most often when the discs don't work out.

  • Sudden hole-size jumps can scare cats off the toilet entirely — one day it's a big comfortable ring, the next it's a narrow gap that feels unstable
  • Plastic discs wobble and feel unstable under a cat's paws, which makes cats hesitant to commit to squatting
  • No flushable litter included, so owners end up buying it separately anyway, which adds cost most people didn't plan for
  • Training often stalls at the final disc stage, right when the hole gets small enough to actually reach the bowl

None of this means the idea behind the Litter Kwitter is bad. Toilet training itself is a great goal. It's the execution that trips a lot of cats up, especially nervous ones or kittens who need more time to adjust.

The Cat Throne System As A Smoother Alternative

If the disc-jump problem is what's holding your cat back, a step-stool-based system solves it differently. The Cat Throne System was built around the idea that cats need gradual changes, not sudden ones. Instead of swapping discs with drastically different hole sizes, the patented clip design lets you adjust the setup in smaller increments. The stool shape also gives cats a footing that feels closer to what they already know from a regular litter box, rather than balancing on a thin plastic ring over water.

A few things make this setup different from what you'd get with a disc kit:

  • Patented clip design adjusts gradually instead of sudden jumps
  • Step stool shape mimics natural litter box footing cats already trust
  • Built for long-term stability on any standard toilet
  • Full training kit priced at $117

Setting it up isn't complicated, but a few steps matter for a good start:

  1. Place the stool over the toilet bowl with the litter tray in place
  2. Let your cat use it normally for several days before adjusting anything
  3. Move to the next clip setting only once your cat seems fully comfortable
  4. Repeat gradually until the tray is no longer needed

Compare that to jumping straight from a wide disc to a much smaller one, and it's easy to see why patience built into the design matters. For a deeper look at what actually makes a system work long term, this breakdown of what makes a cat toilet training system work covers the mechanics in more detail.

Pairing Flushable Litter With Your Training Kit

Whatever training system you use, the litter itself matters more than people expect. Clay litter tracks everywhere, doesn't flush, and turns into a mess once your cat starts using a stool or tray positioned over the bowl. Tofu-based litter solves most of that. It clumps like clay but breaks down enough to flush without clogging pipes, which matters a lot once your cat is using a toilet-adjacent setup instead of a floor box.

Tuft & Paw's Tofu Flushable Litter is low-tracking and 99% dust-free, and one bag is usually enough to get one cat through the full training process. It comes in Charcoal (unscented) or Lavender (light natural scent).

Feature Tuft & Paw Tofu Cat Throne Tofu
Price $28 $23
Scent options Charcoal, Lavender Unscented
Bag size Standard bag 5.5 lb or 1 lb sample


The Cat Throne Tofu Flushable Litter is a large-grain option built for bulk use, which works well for multi-cat households or anyone who wants a bigger supply without reordering constantly. Both options avoid the plastic and clay waste that ends up in landfills, something eco-conscious owners tend to care about a lot once they start comparing what's actually in a bag of standard litter.

If you're still weighing whether toilet training beats sticking with a box long term, this comparison of cat toilet training versus litter box use lays out the tradeoffs plainly. And if you want the full rundown on training kits before buying anything, the guide to the best cat toilet training kit is worth a look before you commit to one system over another.

Litter Kwitter Versus The Cat Throne Head-to-Head

Most cats fail toilet training not because they're stubborn, but because the jump from litter box to toilet seat happens too fast. That's really the whole story when you compare these two systems. Litter Kwitter uses a set of plastic discs with shrinking holes, and cats are expected to figure out the size changes pretty quickly. The Cat Throne uses a clip system that moves the litter tray up in smaller stages, which gives cats more time to adjust without freaking out. Vets and trainers tend to side with the slower method because sudden changes in bathroom routine can cause cats to avoid the toilet altogether, sometimes for weeks.


Feature Litter Kwitter The Cat Throne
Price ~$40 $117 
Method Disc swap, faster steps Clip system, gradual steps, permanent
Materials Plastic discs Toilet seat, Cat Throne seat, Trays,  flushable litter, tongs, brush included
Training Success Mixed, higher failure reports Higher, more humane for cat


Price is where Litter Kwitter looks like the better deal on paper. But a lower price doesn't help much if the cat gets scared off the toilet and you're back to buying a litter box anyway. That's the part people don't think about until it happens to them.

  • Cats stressed by fast transitions often regress to old habits
  • Gradual step systems tend to need fewer restarts
  • Pairing training with flushable litter, like our Tuft & Paw Tofu Litter, keeps the mess low during the switch
  • Higher upfront cost can be cheaper long term if it means fewer wasted attempts

If you're the type who wants to try things once and move on, the slower method usually wins out. Gradual transitions reduce stress, and less stress usually means fewer accidents outside the box. Flushable litter paired with training also cuts down on cleanup during the messy middle stages. And honestly, fewer failed attempts means less money spent overall, even if the starting price looks steeper.

Wrap-up: Picking The Right Toilet Training Path

So here's the deal. Litter Kwitter can get the job done, but a lot of cats get spooked by how fast the rings disappear, and owners end up starting over more than once. That's frustrating for everyone, especially if you've got kids watching the process or a full house to manage. If you want to compare methods side by side, this breakdown of toilet training versus rings lays it out pretty clearly.


The Cat Throne System takes a slower, steadier approach instead. It's built so your cat moves through each stage without feeling like the ground shifted overnight. Pair that with something like our Tuft & Paw Tofu Flushable Litter, and you've cut down on tracking, dust, and the whole hassle of scooping clay litter while your cat adjusts.

A few things worth remembering before you start:

  • Cats respond better to gradual changes than sudden ones
  • Flushable tofu litter means less mess during the messiest phase of training
  • Having the right stool setup from day one saves you from restarting later

Litter Kwitter And Toilet Training FAQs

Toilet training a cat brings up a lot of questions, and honestly, that's a good thing. It means you're thinking it through before you spend money on a kit that might just sit in your closet. Here's what people usually want to know before they start, whether they're looking at Litter Kwitter, another brand, or a step-based system like The Cat Throne.

How long does toilet training usually take

Most cats take somewhere between four to eight weeks to fully switch over. Some quick learners get there in three weeks, while more stubborn cats can take a couple of months. Going slow and not skipping steps actually speeds things up in the long run, since rushing tends to cause setbacks.

Can any cat be trained regardless of age?

Younger cats usually pick it up faster, but older cats can learn too; it just takes more patience. Cats with joint issues or balance problems might struggle with the higher ring systems some kits use, so that's worth keeping in mind for senior cats.

Is flushable litter safe for septic systems?

Not all "flushable" litter is actually septic-safe, so this is worth checking before you buy. Tofu-based litters tend to be the safer bet since they break down faster than clay or crystal litters. Both the Tuft & Paw Tofu Flushable Litter and the Cat Throne Tofu Flushable Litter are septic-safe, so you don't have to guess.

What if my cat refuses to use the toilet

This happens more than people expect, and it's usually not a sign the whole idea is a bust. A few common fixes:

  • Move back a step and give it more time before advancing
  • Check if the toilet lid or ring feels unstable to your cat
  • Make sure the bathroom is quiet and easy for your cat to access

If your cat still won't budge after trying these, it might just mean toilet training isn't the right fit, and that's okay too.

What's the difference between Litter Kwitter and other kits

Litter Kwitter uses a ring system that sits directly on the toilet seat, while newer systems like The Cat Throne use a step stool design that some cats find more stable. Neither is perfect for every cat, so it really comes down to what your cat feels comfortable with.
