What it is

A 4.5-kilogram bag of plant-fiber tofu clumping litter from Trixie.

The case for a small bag

Litter is the one purchase in this niche where the cat has a veto. A cat that dislikes the texture will tell you within a day, and finding that out with 4.5 kg (9.9 lb) is considerably better than finding it out with 10.8. Once the switch holds, the big bags are cheaper per kilo.

Transitioning properly

Mix rather than swap. A quarter new litter for a few days, then half, then most. Cats object to sudden substrate changes more than to the substrate itself, and an automatic box is already asking them to accept something unusual.

The questions owners ask

How do I change litter without upsetting the cat?

Gradually. Mix a quarter of the new litter into the old, then half a week later, and so on. Cats notice substrate changes and a sudden switch is one of the ways a working box stops working — which is also why a small first bag is the right purchase.

Is Trixie tofu the same as the FUKUMARU?

Both are tofu-based clumping litters and both behave similarly in an automatic box. The difference at the shelf is bag size and price per kilo: this is the 4.5 kg (9.9 lb) test bag, those are the 10.8 kg (23.8 lb) monthly ones.

Can I mix litters?

During a transition, yes — that is exactly how a transition works. Permanently, it makes clumping unpredictable, and unpredictable clumping is what jams automatic boxes.

    • Lighter to carry than clay for the same number of days
    • Several litter box makers exclude tofu litter from warranty because the grains swell — check your manual

    Best for: A clumping automatic box in a flat, where weight and dust matter as much as price.
