Biodegradable? Maybe. Compostable? No!
We've used Oko Plus for our two cats for two years now, and have been adding it to our compost bins in the garden with care - ie in mixed layers, not huge quantities at once. This used litter has NOT rotted down, contrary to how this product has been advertised. We are very disappointed at having now been forced to throw it out with the rubbish. I'll be taking this point up with the manufacturers. PS Otherwise, it's great...
