Before using Cat Natural Biolitter, clean the cat toilet or birdcage. Pour a layer of about 2 cm of litter into the cat toilet or birdcage. Remove the cat’s or bird’s solid droppings regularly and if needed, replace the whole litter. When using Biolitter for the first time, we recommend to add a scoop of litter that your cat used before. Biolitter can be flushed down the toilet or composted in the garden. Before flushing, please read the terms and conditions of your water provider.
