What litter is safe at each age?

A kitten's age determines what litter you should use. Here's the clear breakdown.

Under 4 weeks

Kittens under 4 weeks old don't use a litter box at all. Their mother stimulates elimination. No litter needed at this stage.

4 weeks – 4 months

Use non-clumping litter only at this stage. Very young kittens may ingest litter while grooming — clumping bentonite can cause intestinal blockages if swallowed in quantity. Use unscented non-clumping clay or pine pellets.

4 months and older

Kittens aged 4+ months can safely use clumping bentonite litter like Sanking Carbon Fine Bentonite. By this age, they've learned not to eat litter and their digestive systems are robust. This is when you transition to the best litter.

What to avoid for young kittens

Scented litters

Strong fragrances can overwhelm a kitten's sensitive nose, causing them to avoid the litter box entirely. Always choose unscented for kittens.

High-dust clumping clay (under 4 months)

Dusty litters can cause respiratory issues in young kittens. If you must use clay for young kittens, choose a 99% dust-free option.

Silica / crystal litter

Crystal litter pellets are hard and sharp-edged. Young kittens with tender paw pads may find them uncomfortable and refuse to use the box.

Scoop too deep for kittens

Use a low-sided litter box for kittens — they can't climb over high walls. Depth shouldn't exceed 2 inches until they're older and stronger.

How to transition kittens to Sanking

Once your kitten reaches 4 months, here's how to switch them to Sanking Carbon Fine Bentonite.

Week 1

25% Sanking

Mix 75% of the old litter with 25% Sanking. Let your kitten explore the new texture without rejection.

Week 2

50/50 Mix

Equal parts old and new litter. Most kittens adapt well by this stage and show no preference.

Week 3

75% Sanking

Almost fully transitioned. Your kitten will be accustomed to the Sanking texture and scent.

Week 4

100% Sanking

Full transition complete. Enjoy superior clumping, activated carbon odor control, and less maintenance.

Kitten litter FAQs

Kittens aged 4 months and older can safely use clumping bentonite litter like Sanking. Under 4 months, it's safer to use non-clumping litter as very young kittens may ingest litter while grooming themselves. Once they reach 4 months, you can begin transitioning them to Sanking over 3–4 weeks.

Yes. Activated carbon is a natural, inert mineral that poses no toxicity risk to cats or kittens. It's the same type of carbon used in water filters and medical detox treatments. In Sanking litter, it's infused into the bentonite granules to absorb odor molecules — not released as a substance your kitten would interact with.

Use a shallow, low-sided litter box for kittens under 6 months. They should be able to step in and out easily without climbing. A box with walls of 3–4 inches height is ideal for young kittens. As they grow, graduate to a standard deeper box. The box should be at least 1.5x the length of your kitten.

For young kittens (under 6 months), fill to 2 inches depth. For older kittens and adult cats using Sanking clumping bentonite, 3–4 inches gives enough depth for proper clump formation without touching the box bottom. Too shallow means clumps stick to the bottom; too deep wastes litter.
