Modkat Litter Box Liner Refill – Which Refill Is The Right One?

These reusable litter liner bags are specifically made to fit Modkat Litter boxes.

In total there are 5 different liners for Modkat litter boxes. If that sounds confusing, we have simplified things by explaining which Modkat liners go with which Modkat litter boxes.

The fit of these liners is perfect because the liners are specifically designed to fit the Modkat litter boxes.  

Plastic liners that are generic, to fit many different types and sizes of litter boxes will not have the same snug fit simply because it is not possible to make plastic liners that fit all litter boxes perfectly.

There are however, different types of cat litter liners, for example drawstring, elastic, biodegradable and sifting cat litter liners.

All of those liners are explained here in more detail.

The Modkat liners are named A, D, C, F, G.

1. Modkat Type D Liner. Refill for Modkat XL when using the front entry
2. Modkat Type C Liner. Refill for the Modkat XL when using the top entry
3. Modkat Type G Liner. Refill for Modkat Tray Litter Box
4. Modkat Type F Liner. Refill for Modkat Flip Litter Box
5. Modkat Type A Liner. Refill for the original Modkat Top Opening Litter Box

1. Modkat Litter Box Type D Liner

This is the Modkat Type D liner.

It is the refill for the Modkat XL when using the front entry option.

This is what the refill looks like.

The reusable insert is designed to be a perfect fit for the Modkat® XL Litter Box, Top or Front-Entry Configurable.

The liner has hooks, which hook onto the hooks, that are inside the litter box. 

The liner is constructed of rip resistant tarpaulin.

The price which may seem high at first glance is for 3 liners and each liner will last approximately three months. 

When you look at the cost, taking into account how long each liner lasts, it does make a difference.

Pros

These bags are very sturdy compared to a normal plastic litter box liner.  They frequently last longer than the recommended three months.

Cons

The shaped front edge in this model appears to be a cut raw edge, whereas previously it was a seamed edge.  Hopefully this problem is temporary and will be rectified.  It won’t affect how the liner works but may affect the longevity of the liner near the raw edge. 

Specifications

The liners measure 20 x 16 x 15H in inches.  There are 3 liners included in the refill pack.

2. Modkat Litter Box Type C Liner

Liner D is used in the Modkat XL when the front entry configuration is used.

The liner C is used in the Modkat XL when the top entry configuration is used.

The front flap on the litter box, locks the liner in place.  This can be seen in the image.

As with the other Modkat liners, the sturdy and reusable liners make it easy to empty the litter. The liner is cleaned and then reused for up to 3 months (or longer).

Pros

This tray has a splash guard which makes the sides of the box tall which is good for high pee-ers.

Cons

The tarp does not cover the high guard area and urine may get trapped between the guard and the liner.  This is a common problem with this type of set up and cats that are high pee-ers.

Specifications

The type G liner measures 20 x 14 x 9H in. (50.5 x 35.5 x 23H cm)

How To Clean A Modkat Litter Liner

The Modkat liner makes cleaning up after a cat much easier, but how do you clean it? 

Follow these steps to thoroughly clean the liner to ensure that it lasts the three months suggested by the manufacturer or hopefully longer, as is often the case. Look after the liner to get the best use.

1. Put the liner in a tub of warm soapy water and agitate to remove debris. Scrub with a brush if necessary to remove dirt.

2. Rinse the liner thoroughly with fresh water to remove all soap residue.

3. Hang up to dry, put on a drying rack or place in the sun for quicker drying.

4. Once dry, fold the liner into thirds lengthwise and place it back inside its original bag for storage or place back into the litter box.

5. Store your Modkat Litter Liner away from direct sunlight and moisture sources like dishwashers or washing machines.

When Do You Need To Replace Your Modkat Litter Liner?

When is it time to change the liner in your Modkat litter box?

One way to tell if it’s time for a new one, is by looking at the bottom of the current liner and checking for any tears or holes.

If there are none, then you’re good!  

If the liner is looking frayed, it will be more susceptible to tearing so keep an eye on it. 

Also keep in mind that 3 months is the recommended time from Modkat before changing liners. There can be bacteria that lingers on liners if they are not cleaned properly.

Make sure that the level of litter is maintained at 2-3 inches and that the litter box is scooped regularly.

Wash and store the liners carefully, to extend the life of the liner and avoid unnecessary purchases.
