Litterbox Mods for Severely Disabled Kitties

A recent forum post reminded me that I’ve wanted to update my litterbox modification advice based on some trial and error tips I’ve developed over the last many months. So, here we go! Litterbox tips and tricks for severely disabled kitties! (E.g., poor Feta, who still essentially has 2.5 legs, since she can’t bend her remaining hind one.)

It’s often a good idea to have more than one box.

A beautiful living room centerpiece, no? Real conversation-starter!

With Feta, since she sits her bum directly down on the litter, being able to potty in a CLEAN box is extremely important. Since she likes to pee and poo at the same time of day (cats, go figure) this means she often needs 2 separate boxes, so she can pee in one and poo in the other. Much as I dislike having DOUBLE the mess and eyesore, it’s better than cleaning up messes outside of the box!

Mats, mats, and more mats!

Inspector Dog says, “Yes, mats are acceptably placed. I shall now poop on them.” Thanks, Inspector Dog :/

I now have two plastic floor protectors underneath my entire setup, for ultimate floor protection, with puppy pee pads underneath in case of spillage. (Once Feta missed the box and it went under the plastic, and that was gross and unhappy.)

Plastic over the rug! Since this photo, I have added the additional base-layer of pee pads – unattractive, but useful.

“Open” access is critical. Wings and walls are a no-go.

This obviously varies by kitty, as some actually prefer having something to lean up against. Feta, however, has trouble maneuvering – it is hard for her to turn around – and so she needs an “open floorplan” to avoid feeling trapped and panicked. This means Flat, no wings, no walls. For example, this is a no-go for Feta:

Feta says this is UNACCEPTABLE!

Again, this is a big bummer since obviously it leads to a lot of litter spillage, but it’s still better than cleaning up messes directly on the floor.

Now, it’s time for arts and crafts! Make your very own artistic box for your cat to pee and poop in!!!!

Feta Cat does not approve of this activity, and its distraction from providing her with food and ear rubs.

Instructions for Feta-Approved DIY Handicapped-Accessible Litterbox

With all these tips in mind, this is how I am currently making Feta’s boxes. Using this method, they last pretty well, and I generally only replace them every few months.

Supplies needed: Packing or duct tape, superglue for reinforcement, scissors or knife (or both) for cutting cardboard, waterproof shelf liner or other “waterproofing” material (note: when I bought this from Amazon, it was around $6; if what you are seeing is expensive, there are sure to be cheaper alternatives)

Step 1: Obtain Box (Feta suggests buying cat food, cat treats, and cat toys from Amazon or, as they both have excellent boxes)

Step 2: Cut 3 walls of the box down to size. Save one of the “short flaps” to reinforce the bottom of the box. The height of the walls will depend on the mobility restrictions of your cat. For Feta, we’re currently at about 2-3″ high. Obviously, the taller the sides, the harder for your cat to get in, but the easier for you to clean up. (Leave one wall full-size to give you a “backsplash” wall, to help keep things clean.)

Step 3: Remove cat from box.

Seriously, Feta, could you NOT?! I am trying to use that!! “I am cat. This is box. What did you expect.” -Feta

Explain to the cat that the box is destined for potty time, NOT playtime.

Succumb to the irresistible charms of Cat and play Box with your kitty for a few minutes.

Step 3: Take the “short flap” that you set aside from Step 2, place it in the “gap” in the middle of the box bottom, and tape them together securely. The point of this is to have a nice, flat bottom without any little “cracks” that could get ripped by a vigorous litter-digger (like Feta >:( )

So flat! So taped! Much wow.

Step 4 (the hard part!): Cover the box in your waterproofing material. If your cat is a big “digger,” make sure to have as few seams as possible, and reinforce the seams with superglue. This means fewer, bigger pieces of plastic are better than smaller ones. Overlap is good, except that the plastic often sticks to cardboard better than it sticks to itself, so it can get dug up more easily.

Note: if you don’t have a waterproofing material, you can “waterproof” by covering the box with duct tape or packing tape, but because of the number of seams, this method doesn’t last as long. Also, it’s more expensive.

As I noted before, the plastic liner seems to stick to cardboard better than it sticks to smooth plastic. So, I cover the smooth areas (like tape, or the seams where it meets other layers of plastic) with a bit of superglue for extra sticking power.

See the faint squiggle of superglue?

The corners, obviously, are especially tricky. I end up using multiple pieces of material, again trying to avoid seams as much as possible, and adding superglue to make sure they stick together extremely well. Along the seams and along the corners of the box are where problems are going to show up first, so I spend a little extra time trying to protect these areas very, very well so I won’t have to replace the entire litterbox for a while.

You can see in the above picture I also went up the side walls of the box and over the lip. This is optional, but I feel like it helps keep things a little cleaner, especially if your kitty is prone to… erm…. aiming problems.

Once all this is finished, you are done! Admire your handiwork. Add additional waterproofing to the “backsplash” if you like, and you can optionally extra-secure the edges on the outside of the box with more tape.


Such a work of art! National Gallery, here we come!

Now clean the superglue off your fingertips. How did you get so much all over your fingertips??



Finally, fill your beautiful new box with your kitty’s favorite litter, set out your multitude of floor protectors, and watch with conflicted joy and annoyance as your beloved kitty urinates and defecates all over your brilliant creation. Congratulations!!

Final note: why my obsession with the seams? If your kitty digs into the litter and is able to lift up a bit of the plastic liner, the litter will get underneath it and start to give you a big mess. Behold:


So secure your seams, everyone! Now go forth and make some beautifully-functional litterbox art.
