Frequently Asked Questions
Our cat litter is primarily made from sustainably sourced walnut shells. Walnut shells are an excellent natural alternative to traditional clay litters because they are biodegradable, super absorbent, and gentle on your cat’s paws.
On average, a cat uses around 3kg of clay cat litter per week. However, Nature’s Calling, made from natural walnut shells, offers superior absorbency and quick-clumping action while absorbing odours three times better than clay. As a result, you’ll likely to use less of our eco-friendly litter compared to a clay-based option —meaning it lasts longer and reduces waste.
Yes, our walnut shell cat litter is safe for cats. It is free from chemicals, fragrances, additives, toxins and silicas making it a healthier choice for your feline friend. The natural absorbency of walnut shells also helps to control odours effectively.
The most common nut allergies are triggered by ingesting nut proteins, so if this is your type of allergy, there is little cause for concern, as Nature’s Calling Cat Litter is not intended for human or pet consumption. However, it is highly recommended to wash your hands after handling any cat litter, as contact with cat urine or faecal matter can pose health risks. For those at risk of anaphylaxis—a rare but serious allergic reaction caused by airborne particles—we strongly advise against using our cat litter to ensure your safety.
Walnut shells are highly absorbent and can lock in odours for extended periods. Their natural properties make them effective at managing liquid and reducing ammonia smells, keeping your cat litter tray fresher for longer.
Our walnut shell cat litter is designed to be low-dust, which is better for both your cat’s respiratory health and your home environment. It reduces the amount of litter dust that can be tracked around the house or inhaled by your cat.
Add 4cm of Nature’s Calling Cat Litter to a clean litter tray, then top it up with 2–3cm of your current cat litter to cover it. With each litter change, gradually reduce the amount of your existing litter. Most cats adjust comfortably to the new litter within one or two changes.
