Many years ago I used a mineral cat litter (Thomas) because the shop across the road sold it and I didn't have to carry it far to my home.
One winter, we had thick snow not unlike some of us have just had.
I was taking a bag full of "dirty" litter to the dustbin, slipped on the path and dropped the lot. It went EVERYWHERE!
Very embarrassed I got up, dusted myself down and kicked the cat litter about in an effort to hide what Id done.
My elderly neighbour appeared and said "Ooh, well done, Dear- Thank you for gritting the path!!" I didn't have the heart to confess, and it actually worked quite well.
I now use the wood pellet litter and it goes out , double bagged, in our ordinary "landfill" rubbish
