DIY Cat Toilet / Potty Trainer Sturdy and Re-usable!




Introduction: DIY Cat Toilet / Potty Trainer Sturdy and Re-usable!

I have two cats, I hate doing the litter box, and I have a spare toilet in the basement that no one uses. I tried the CitiKitty a few months back (it was gifted to me) and it didn't work out because at the time I was sharing the litter covered bathroom with the cats and lost patience. This time around, I didn't want to spend $30 on a one time use, flimsy vacuum formed solution and decided to make my own. I'm surprised there aren't any good DIY solutions out there. This requires either a laser cutter, or a router / bandsaw )

Total Project Cost: ~$10

- 5 Gallon Pail ($3 @ Home Depot)
- 8x 3/8x2-1/2” Bolts (<$3)
- 8x 3/8” Nuts (<$1)
- 16x 3/8” Washers (<$1)
- 2x Sheets of 1/8” 12x12 ABS ( I opted against wood because it would soak in urine ) ( 8 Pack @ $8 )

- Plastic Weld / Plastic Glue


- Cut bottom 2-3” off of pail (I used a table saw). This is your bowl.

- Cut 8” diameter hole out of bottom of bowl. I used a multitool

- drill 8 equidistant 3/8” holes around the perimeter of the bowl, 5/8” below the rim.

- Attach hardware as pictured with a washer on either side of the bowl rim.

- Cut out pattern from ABS. I used a 40w laser. (PDF attached)

- Glue matching pattern pieces to each other. I used Plastruct. This step is best performed with the pieces nested because the tolerances are so tight, just be careful not to glue the wrong pieces together.

- Let bonds cure, test by pressing. If it comes apart, re-glue. You don't want to chance your cat falling into the toilet and being traumatized. Thanks to the many points of contact (bolts) and the 1/4" of ABS sheets, there is no flex whatsoever. Cats are smart, I reckon they don't trust a flimsy platform over a known pool of water.

- Train your cat. Follow instructions for a commercial product like CitiKitty or Litter Kwitter. Gradually get cat to use toilet box without holes, then slowly remove a ring at a time. The nice thing about this design is the ability to go back a step or start over if things go awry. You want to use a "flushable" litter like Cat's Pride.

    do you still put some litter in there once you take out the center hole?

    Yeah, you want to keep litter in it all the way to the end.

    See if it works for dogs.
