A Lump Of Sort Of Coal
This lump of coal in the form of a refrigerator deodorizer might be a long way to go for a joke, but think of the funny look on the face of your naughtiest gift recipient when they open up a lump of coal! This is actually a white charcoal made from Korean oak, and it naturally purifies the air. This block is designed to be used in refrigerators, but I’m thinking putting one by a litterbox might not be such a bad idea. The block will last for years, and when it’s finally done, you can crush it up and mix it in with soil to fertilize your plants. A lot more snazzy than a box of baking soda, at the very least.
