KittyLitter MALM
Intro: KittyLitter MALM
Having cats means also having a litterbox standing around somewhere and several times a day having a distinct smell floating around your home.
Searching for solutions to the problem I saw various hacked IKEA pieces for this purpose. So one day I was heading to the flat-packed-furniture-shop to look out for my own hacking victim…
And there it was: The 3 drawer MALM dresser!
Searching for solutions to the problem I saw various hacked IKEA pieces for this purpose. So one day I was heading to the flat-packed-furniture-shop to look out for my own hacking victim…
And there it was: The 3 drawer MALM dresser!
STEP 1: Materials and Tools
Materials:
Tool:
- 3 drawer MALM
- catdoor
- litterbox
- some sheets of black PVC in various sizes
- two pieces of L-shape aluminum rail (1x1x43cm)
- one sheet of plywood or MDF 0,4x76,5x43,5cm
- small air inlet grill
- filter mat (activated carbon)
- plasticbox or cup
- screws
- small angle brackets
Tool:
- all tools necessary for IKEA assembly
- jig saw
- carpetknive
STEP 2: Catdoor Placement
Measure carefully, where the drawerslider on the inside of the MALM goes. Then put the catdoor-stencil around 2 or 3 cm on top of it. Like this it's not to high for the cat to enter, and the cutout on the drawer can easily be made. Cut out with the jigsaw and then mount the door according to instructions, but take out the swinging part, or at least be sure to fix it in locked position.
STEP 3: Assembly
Assemble the MALM according to instructions, but leave out the middle drawer-sliders and the second-from-bottom horizontal piece.
Before putting the backwall into place, fix the two aluminum rails below the upper drawersliders (the L has to be upside-down)
Assemble TWO of the drawers, put aside the parts of the third, you will need them later.

STEP 4: Hacking
Put one of the assembled drawers into the lowest slot of the dresser and mark the position of the catdoor from the outside. Then cut out the marked piece with the jig saw.
Next take the left over parts from the third drawer. I used the sides to fix the middle front to the lower drawer. One of them I cut in half lengthwise to use as a kind of filler to better fit the letterbox into the drawer. The gap between the frontparts I covered with a stripe of black PVC, fixed into place with double sided tape.
To keep the letterbox from moving around in the drawer, I built a frame with PVC-stripes and L brackets.
Use the carpetknive to cut a hole in the backwall, to fit in the air inlet grill. Mount grill and filter (I screwed three pieces of PVC-sheet to the outside of the wall to counter the grill and sandwiched the filter mat in-between)

STEP 5: Final Touches and Training the Cats
To stop the smell from leaking into the top drawer, I put a sheet of MDF (precut to size) onto the L-shaped aluminum rails.
To have the cleaning tools ready I added a small plastic box to hold the waste bags an a screw to hang the shovel.
To clean the letterbox, you need to pull the drawer almost fully out, so it's not hold horizontally anymore by the sliders. So I decided to screw the leftover horizontal piece to the bottom of the drawer, to avoid to much tilt.
Be smart and train the cats to use the door, or you will end up like me with a pile of smelly catpooh on your carpet…
It is also a good idea to remove the small magnet, which hold the swinging door in its vertical place, to make it easier for the cats to access their privat place! ;-)

If you really want to vent the thing outside the house, you could use a dryer vent, and install it through the wall. (Some fan testing would be good to ensure that the fan has enough power to open the flap.) The only problem with this is that you'll have to borrow a 4-1/4" hole saw and arbor, or shell out $50 for a set. Or you could cut a round hole with a sawzall, which can be rented, but you'll need a steady hand, because the standard blades are too long to poke into a 2x4 stud wall without hitting the wallboard on the inside of the wall, if you press the shoe of the sawzall against the exterior siding. Or you could just use a keyhole saw and do it by hand.
-- For renters, a dryer vent could be installed through an insulated panel you make to fit into the bottom of a window, but that would require some extra work to make the window lockable and to seal the top of the sash. (A strip of foam rubber would do for the latter.) Some flexible vinyl ducting would be needed for this. Unfortunately, this approach would make the window unusable in the summer.
-- Fan trigger? Motion sensor with a 10-minute timer. It takes time to get rid of that smell.

Really Good Idea This!

If your willing to share, I would love to see a picture of how you mounted the fan... ;-)

I've wondered if somehow I could rig an exhaust line to the exhaust fan in the ceiling of my bathroom (where I keep my litter boxes) ... anyone got an idea about that? Or at least share the "exhaust stack" that already goes up into attic but install the little computer fan motor that was mentioned?
I'm in a rental so I can't put significant holes into walls or ceiling ... but would sure love to be able to exhaust not only odors but also litter dust.
Thanks!

But thinking of the exhaust in the ceiling, I would try to make a exhaust pipe up there along the wall and ceiling out of a flat and square kind of tube to make it look "nice"

Since then I usually put a leftover piece of carpet in the gap between litterbox and door, so most of the litter stays in.
And by the way: Thinking is GOOD! ;-)
