Genius Litter Pros
Monitors Urinary Health
The standout feature of Genius Litter lies in its health-monitoring capabilities. By changing color according to your cat's urine pH, it acts as a proactive tool for detecting urinary issues early on.
Low Dust (vs clay)
Compared to traditional clay litters, Genius Litter has a significantly lower dust content. This is a great feature for cats and humans with respiratory issues and helps maintain a clean home. However, Genius Litter is slightly dustier than some natural litters like tofu pellets and cassava litter.
Easy to Clean
Genius Litter is non-clumping, which means less scooping. To maintain the litter box, cat parents only scoop solid waste and give the litter box a stir once or twice a day to ensure all urine is absorbed by the crystals. According to the brand, one bag of litter should last a full month before needing to be changed.
Available as Subscription or One-Time Purchase
Genius Litter provides the flexibility of both subscription and one-time purchase options. This makes it easy for cat parents to try it out for a month, then subscribe afterwards.
tuft + paw Really Great Cat Litter Pros
Very Low Tracking
Really Great Cat Litter is one of the lowest tracking litters on the market. Unlike particle litters, the small tofu pellets barely get caught in your cat's toes or fur, keeping litter mess to an absolutely minimum.
Really Great Cat Litter is extremely low dust, even compared to other “low dust” litters. Tofu pellets are inherently less dusty than silica gel because they’re made from a plant-based fiber rather than a mineral.
Unlike Genius Litter, Really Great Cat Litter has a clumping formula. Most cat parents are used to clumping litters, which enable all waste (solid and liquid) to be removed from the litter box.

Flushable and Biodegradable
One of Really Great Cat Litter’s best features is that it’s flushable and biodegradable. This makes it extremely easy to clean up and an attractive choice for eco-minded cat parents seeking sustainable options.
Note: Only flush cat litter if your cat lives exclusively indoors and does not eat raw cat food. Flushing cat litter is illegal in California.
Really Great Cat Litter is made from soybean fiber which would otherwise be food waste, making it a great eco-friendly option. Crystal litters, by comparison, are made from silica which must be mined and contributes to habitat degradation and water pollution.
Really Great Cat Litter is not a cheap litter, but it is more affordable than Genius Litter. Really Great Cat Litter comes in at $3.05/lb, while Genius Litter is $5.00/lb.
Both Genius Litter and Really Great Cat Litter are exceptionally absorbent. Genius Litter's silica gel efficiently locks in urine and allows water to evaporate, while tuft + paw Really Great Cat Litter's tofu pellets absorb liquid waste like sponges.
Both the silica gel particles of Genius Litter and Really Great Cat Litter’s tofu pellets are lightweight, easy to handle, and come in manageably-sized bags.

Safety is paramount, and both litters prioritize the well-being of cats and humans. Genius Litter's amorphous silica gel and tuft + paw Really Great Cat Litter's soybean fiber are non-toxic and totally safe for cats and humans. Clay cat litter, on the other hand, is known to contain crystalline silica dust, which can be carcinogenic if inhaled.
Good Odor Control
The porous structures and absorbency of both litters contribute to effective odor control. Silica gel absorbs urine, traps smelly compounds, and allows water to evaporate. Tofu litter is also highly absorbent, but Really Great Cat Litter also contains activated charcoal to supercharge its odor control.
