I designed and made my own kitty litter trap.
It’s similar to a tea tray base with rubber grated tiles.
I made 3 because I have 3 litter boxes.
Here is a video:

Here are more pictures:
And here are the instructions:
materials: plywood and ~1/2 x 1.5" wood planks with 3d printed framing (other framing would work though) plus rubber tiles that were 11 x 11 inches.
I clipped off some of the connectors from the tiles using clippers commonly used with 3d printers. those little ones that are common.
the 3d parts i designed in tinkercad. I made them 1cm thick.
You could use 1cm wooden square dowels instead or some other trim or framing that’s similar thickness.
Steps:
First: measure two tiles. measure your framing width. Multiply by 2 and add that to the tile size width and length. And that’s how big you need to cut your plywood piece to be.
Then cut two “legs/base” pieces that are the length of the short side of the plywood piece. I suggest using pretty long screws and to drill out a counter sink so the screws are flush. otherwise your framing won’t lay flush.
Also if you use really thin plywood or mdf, maybe make a 3rd base leg to help the warping which is worse in thinner wood/mdf. Put it in the middle between the other two oriented the same direction.
The only downside is you have to buy the tiles in packs of 9 or more so if you only need 2 you will still have to buy 9.
The design works very well. I’m looking forward to less litter all over the floors.


My solution to this problem was to build an open-top wooden box enclosure with 1 ft high walls around the litter box. Along the entrance, the wall is lower (about 6") and I attached 2" or 3" paint brushes pointing upwards to brush litter off the undercoat as the cats exit the enclosure. The cats hated it at first and would jump over the brushes but over a short period of time, laziness won and they adjusted to the sensory experience. I haven’t noticed stray litter since.
can I get a picture?
Sure
I had forgotten when I wrote my first comment that on this revision of the enclosure I cut the bristles off a single paintbrush and glued them to a board, then glued another board to the other side. I do not like this as much as the first enclosure in made in the past when I bolted on several full brushes.
I am definitely going to try this out. Will report back if successful. Do can’t prefer synthetic or natural 🤣?
That’s pretty ingenious
