Quick answer: Clumping clay litter is the most popular choice for odour control and easy cleaning. Silica gel litter lasts longest between changes. Natural litters (wood, corn, paper) are more environmentally friendly but may track more. Most cats prefer fine-grained, unscented litter.

Why Cat Litter Choice Matters
Cats are particular about texture, scent and cleanliness. The wrong litter leads to tray avoidance. The right litter makes cleaning easier, controls odour better and keeps your cat happy to use the tray consistently.
How We Compare Cat Litter in the UK
We review publicly available product information, material composition, odour control claims and dust levels. We do not claim to have physically tested every product unless explicitly stated with evidence.
Types of Cat Litter Available in the UK
Clumping Clay Litter
Forms solid clumps around urine and faeces, making scooping easy and efficient. The most popular type in the UK. Good odour control. Heavier than alternatives. Produces some dust.
Best for: Most cats and owners. The default recommendation for ease and cleanliness.
Non-Clumping Clay Litter
Absorbs urine without forming clumps. Cheaper per bag but requires more frequent complete changes. Less convenient but perfectly functional.
Best for: Budget-conscious owners, kittens (who may eat clumping litter).
Wood Pellet Litter
Compressed wood (usually pine) pellets that absorb urine and break down into sawdust. Natural, biodegradable and often compostable. Good odour control from natural pine oils. Different texture that some cats need time to accept.
Best for: Eco-conscious owners, cats who accept the texture, composting households.
Silica Crystal Litter
Silica gel crystals that absorb and dehydrate urine. Excellent odour control, low dust, lightweight. More expensive per use but lasts longer between changes. Solids still need daily scooping.
Best for: Odour-sensitive owners, cats who tolerate the texture, low-dust requirements.
Paper-Based Litter
Recycled paper pellets or shreds. Very low dust, soft on paws, lightweight. Less effective at odour control than clay or silica. Biodegradable.
Best for: Post-surgery recovery (soft on wounds), cats with respiratory issues, eco-priorities.

Frequently Asked Questions
How deep should cat litter be?
5-7cm (2-3 inches) is ideal for clumping litter. Deeper litter wastes product without benefit. Shallower litter does not form proper clumps and may not cover waste adequately. Wood pellet litter works well at 3-5cm depth.
Can I flush cat litter down the toilet?
No. Most UK water companies advise against flushing cat litter. Even “flushable” litters can block pipes and may introduce toxoplasmosis oocysts into the water system. Bag and dispose of used litter in general household waste.
