Good stuff, but I have just found better
I have been using this since we got our ragdoll kitten and it is impressive stuff. It clumps beautifully and the fact you can wash it down the loo makes it so convenient. If it wasn't for the price I would not look for alternatives. So 5 for the product, 2 for the price. I would give it 4 over all and invite all to buy the Benek clumping biodegradable stuff as it is much cheaper and trails even less than World's Best.
