Earlier in the year, I wrote about my worm bin and how I use it to digest the cat poo and excess litter. More than 6 months later and it is still going strong. There is no smell at all. It sits right by our front door and I have never heard anyone mention it. Honestly, I have been known to direct their attention to the large box of cat poo and explain in excitement how much poop, my little wormies are munching through.
