Cat litter is one of those products that owners frequently choose once — often during their very first cat ownership experience — and then never reconsider, even when significantly better options become available. The litter market in the UK has changed dramatically in recent years, with plant-based and tofu-based alternatives now matching or exceeding traditional clay litters on odour control while being fully flushable and biodegradable.
Choosing the right litter is not simply a question of odour control. Dust generation affects both feline respiratory health (particularly important for brachycephalic breeds and cats with asthma) and human health for allergy sufferers. Tracking — the tendency for litter granules to stick to paws and travel throughout the house — is the single most common complaint among UK cat owners. And weight matters: a 20-litre bag of bentonite clay litter weighs approximately 20kg, while the equivalent volume of plant-based litter weighs 6-8kg.
We’ve tested the major litter types available through ZooPlus UK for 2026, covering clumping clay, crystal silica, and the new generation of plant-based alternatives.
Cat Litter Types Explained
- Clumping Clay (Bentonite): The traditional standard. Sodium bentonite clay absorbs urine and forms solid clumps that can be scooped out, leaving clean litter behind. Excellent odour control, moderate dust, heavy, not biodegradable. The market leader for good reason — it works reliably.
- Non-Clumping Clay: Absorbs urine without forming clumps. Cheaper per bag but requires full tray changes more frequently (typically weekly vs. 2-3 weekly for clumping). Higher waste volume and poorer long-term odour control.
- Crystal / Silica Gel: Silica beads that absorb moisture and trap odour molecules. Extremely low dust, virtually no tracking, and a single tray fill lasts 3-4 weeks for one cat. The highest upfront cost per bag but often the lowest cost per month when calculated correctly.
- Plant-Based (Tofu, Wood, Corn): The fastest-growing category. Made from renewable plant fibres. Lightweight, often flushable, biodegradable, and low dust. Clumping performance varies significantly between brands — the best plant-based litters now match clay clumping consistently.

Our Detailed Reviews
1. Tigerino Premium Clumping — Best Overall
Tigerino is ZooPlus’s own-brand litter range and, after extensive testing, it genuinely earns the top spot. The Premium Clumping formula uses fine-grain bentonite that forms tight, hard clumps within 30 seconds of contact — significantly faster than most branded competitors. The clumps hold their integrity during scooping without crumbling (a common frustration with cheaper clay litters), and the activated carbon variant provides odour neutralisation that lasts 2-3 weeks between full tray changes for a single cat.
Why we chose it: The economy pack pricing through ZooPlus makes Tigerino Premium one of the lowest cost-per-month litters in the UK when purchased in the 2x 12kg saver pack. Performance matches or exceeds branded alternatives at twice the price. View Tigerino at ZooPlus →
2. Tigerino Plant-Based Tofu — Best Eco-Friendly
The plant-based Tofu litter represents the genuine future of cat litter. Made from soybean fibre (tofu manufacturing by-product), it clumps almost as firmly as bentonite, weighs approximately 60% less per volume, generates virtually zero dust, and — critically — is toilet-flushable in most UK plumbing systems (check with your water company if on a septic system). The odour control is surprisingly effective: the tofu fibres have natural odour-absorbing properties that control ammonia without perfume additives.
Why we chose it: For environmentally conscious owners, the lifecycle impact difference is enormous. Clay litter is strip-mined, non-biodegradable, and destined for landfill. Tofu litter is made from agricultural waste, is biodegradable within 30 days, and can be composted or flushed. The performance compromise versus premium clay is now marginal enough that the environmental argument becomes decisive.
3. Tigerino Performance Crystals — Best Low-Maintenance
Crystal litter uses silica gel beads — the same desiccant material found in electronics packaging — to absorb moisture and lock odour molecules into the crystal structure. A single tray fill of Tigerino Performance Crystals lasts approximately 3-4 weeks for one cat without stirring or scooping (solid waste is removed, but the crystals continue absorbing liquid until saturated). This makes it the lowest-maintenance option available.
4. Sanicat Active Gold — Best Budget Clumping
Sanicat Active Gold is a reliable branded bentonite clumping litter that regularly goes on promotion through ZooPlus. The clumping speed is excellent (Sanicat claims “within seconds” and our testing confirms sub-30-second clump formation), and the activated carbon provides solid odour control for the first 10-14 days. It is a strong choice for owners who want brand reliability without premium pricing.
Litter Trays: Does the Tray Matter?
Yes — significantly more than most owners realise. The tray should be at least 1.5x the length of your cat (nose to tail base). Most standard trays sold in UK supermarkets are too small for adult cats, which causes litter to be kicked over the edge (a common “tracking” complaint that is actually a tray-size problem). Hooded trays reduce tracking and contain odour but some cats dislike the enclosed feeling. Open trays with high sides (the Savic Hop In, available on ZooPlus) offer a practical compromise.
