Smart Solution For An Indoor Cat: The Litter Garage

An interior designer and a home re-modeller have figured out how to keep kitty inside without her litter box.  It's a contraption you put together yourself called the Litter-Garage™, but to use it you have to have a wall that adjoins your home and your garage.




First you will need to make a hole in that wall. On the house side of the wall you will mount a step to which a panel is attached containing a cat door.  On the garage side of the wall, you will mount a raised litter box attached to a panel where litter paraphenalia, like a scooper, deodorant, and bags, are also attached.  Between the house panel and the garage panel, there's a chute that is focused downward into the litter box.

When your cat needs to use his box, he enters the chute through the cat door to his destination, the litter box.  Then, when he is finished using the box, he will return through the chute into the house the same way he came in.  However, because the chute is tilted in the direction of the litter box, any litter that has stuck to his feet or fur will slide backwards into the litter box as he moves up the chute.

Very clever design.

The kit comes with a

  • covered litter box 
  • support tray
  • cat door
  • thru-the-wall chute
  • litterscoop, bag holder, hand wipes
  • all necessary fasteners, and (thankfully)
  • step by step instructions

The developers of the Litter Box write that the kit takes about an hour to assemble and that it accomodates cats up to 15 pounds.  For more information, visit  (Update: Unfortunately, this product no longer seems to be available from the manufacturer.)

For those of us without a usable garage wall or those willing to try making it yourself as a DIY project, you may want to consider this almost self cleaning litter box  or this automatic litter box you can buy here

I found instructions for a DIY litter box garage set up similar to the Litter Garage here on Nate and Michelle's 896 YDC Blog.  Definitely worth checking out if you are inspired to create your own.

If you install this between your house and garage, you've just created two major building code violations! If there is only a "pet door" to separate your home from toxic exhaust and chemical fumes, they will enter your home. Any negative air pressure in the home or positive pressure in the garage will pull or force these into the living area. Another problem is that you've just created a entrance for fire from your garage to enter the home and climb up the inside of the wall to the flammable roof. The plastic tunnel, litter box and door will exaggerate the fire and wick it into the living area. You are required to have a 45 minute fire break between your garage and home with no unsealed areas in the wall.

I cannot believe this is being sold. It is unsafe. If you blow off this warning and are unconcerned about your own safety, don't try to sell your home with this installed. It won't pass inspection. It would be fine to install it inside a closet or in a mud room, but not in the garage! Call your local building department and ask about this product for verification.

It's stupid. Whether you have one cat or 2.

I've had 1-5 cats at a time and lived in various places. The litter box placement was never that much of an issue. It was either in a basement, spare room or a closet. The closet was one of the better methods because it kept the dogs out of it.. all you need is one of those cheap closet/storage things you can buy anywhere like Walmart or Target.. put the thing together and leave the back off. The cat goes in through the back and you clean it by opening the door.

Storage bins also make better cat litter boxes..especially for multiple cats. It's bigger and seems "cleaner" to them because there's more litter and digging fun. I had 5 cats using 2, big rubber maid bin. They peed in one and pooped in the other. Cats are weird like that, they weren't trained to do that.

Eventually I moved into a small, studio apartment and caved and bought a $300 Litter Robot which is an automatic box that dumps everything in a bottom tray.

So yeah.. for the amount of money it would cost to build that stupid thing.. there are much better options. Oh, my secret trick is also a raw fed diet which means less poop. Cats fed natural, raw diets like they would eat in the wild poop out tootsie rolls. Not big slops of elephant turds like they do on canned food.
