Step 1: Gather Supplies

1. empty Cat food tub (or any large plastic tub with a lid that seals well)

2. a base tray (I used a cookie sheet that I don't use for baking (it doesn't fit in my oven))

3. a drill & bits

4. Charcoal filters, for a litterbox (I bought the wrong ones & used them anyway)

5. cling wrap or similar product

6. newspaper or plastic drop cloth

Step 2: Wash & Wrap

Wash out your container. -I had to do mine in the tub.

while your container is drying; wrap your base tray in the plastic wrap.

-you don't have to wrap the tray, but in the event of any spill or drips it will make for an easier clean up.

Step 3: Assess & Plan

Check out your filters.

I bought the wrong ones by mistake, but decided to make them work rather than just eat the cost.

(there are probably other resources for this type of filter, this was just the most readily available- read; easiest)

Determine your filter size/shape & use that to guide where you're going to drill.

We are drilling ventilation holes here, so we need a range. The filters cover the holes to prevent odors getting out & pests getting in.

I decided to put 1 filter, with 4 holes underneath centered at the top of ea side & 2 on the lid.

I held the filters in place & marked the corners.

Step 4: Drill!

Using your marks from your filter guide, drill your holes.

Make sure that the hole are covered by the filter, but not obstructed (the filters that I bought had an adhesive pad in the center that I had to work around).

I also drilled holes in the bottom. Use your judgment based on your container, for placement.

**Once all your holes are drilled; empty & if necessary, rinse your bucket. You don't want sharp little plastic fragments mixed into your lovely compost.
