Once upon a time there was a farm kitty named Mamma. She was loved by all the mill workers and when she found herself pregnant, they new she needed to be comfy.
So they put her in a space with heat, food, water, and most importantly, litter!
They decided to try using wheat bran since there just so happened to be a plethora available to them.
Low and behold, it worked like a charm. It clumped up so well! There was no "a cat just peed on chemical dirt" smell.
Seriously kitty lovers, you need to give it a whirl!
15kg of glorious, organic wheat bran.
