The best cat litter for odour will absorb and remove unpleasant aromas. Luckily, cats instinctively know how to do their business. Even as a kitten, they will know how to dig and bury their waste, just as long as a litter tray is nearby. The cat litter tray in your household will get some heavy usage and need a little extra odour control. The last thing you want is to resort to air fresheners to keep your home smelling sweet, especially when there's a simple solution. Use a good quality litter and change it often, this will solve the issue of smelly kitty litter.
A clean and spacious litter tray that's filled with cat litter 7cm deep is perfect for puss to perform their toilette. But to avoid pungent pee there are informed choices you can make regarding cat litter. Wood and paper-based cat litter are a budget option but they don't tend to deal with odours as well as clumping cat litter. If wet urine is allowed to sink into absorbent fibres and sit there, bacteria spread and smells worsen. The upside is that wood and paper-based cat litter tend to be eco-friendly products and with diligent cleaning, you can keep odour at bay.

Silica cat litter is a more expensive option. It's made from an absorbent chemical in crystal form. It has a crunchy texture which some cats may dislike. It's essentially the same moisture-absorbing little packet of silica that you find in items such as leather and electrical goods.
Then, there's clay cat litter that comes in clumping and non-clumping varieties. It has a soft texture and is highly absorbent so it locks in moisture. Clumping litter forms tight lumps so you only remove the soiled litter. Meaning you waste less litter in the long run. It's easy to top up the tray with a little dry litter, stay hygienic, and control odours. Finally, look for a cat litter topper that's made of activated carbon and is highly absorbent. Some cat litter boxes have an activated carbon filter to help reduce odour.
So now you know exactly what you should be looking for, we've rounded up the best cat litter to tackle odours and smells.

Best kitten-friendly litter for odour
It's essential not to give kittens cat litter containing anything toxic as they may well explore it with their mouth — as all babies do. Therefore, opt for an all-natural and non-toxic litter for kittens, such as Blazers Kitten Friendly Cat Litter. Importantly, this naturally pine-fragranced cat litter is antibacterial, preventing the build-up of bacteria that can cause nasty smells.
This is an Amazon's Choice recommended product. A customer remarks that it has a soft texture, which will feel gentler to tiny kitten paws. Also, its fragrance is subtle so that it won't overwhelm them. The wood pellets are smaller than adult litter but just as absorbent and mask odour. There's mixed opinion on whether this is a messy cat litter, but this comes down to how the kitten behaves in their litter tray.
Pros
- All-natural and a good choice for kittens who explore by chewing things!
- Naturally pine fragranced
- Soft on tiny paws so kittens prefer to use it
Cons
- Can be messy

| Materials: | Pine wood |
- Naturally antibacterial
- Environmentally friendly
- Put a layer that's 2-3 cm deep in your kitten's tray
Best antibacterial cat litter deodoriser
Finally, we have a deodoriser that neutralises nasty odours using Felight's Silverfresh technology. It's a great way to keep a litter tray smelling tip-top between changes. Sprinkle this antibacterial powder on cat litter for gentle peony-scented freshness. This helps your cat's litter last longer as the complex silver particles remove rather than mask odour particles.
This is an Amazon's Choice recommended product. For just a couple of pounds, it's a must-try for a household with cats. Customer reviews say that it's cheap and effective. They sprinkle a little on their cat's litter, which keeps the tray smelling fresher for longer. However, some reviews comment that while there is an initial floral scent, it wears off and it's not enough to mask the smell of the litter box. So, while opinion is divided, given the price, it's worth a shot.
Pros
- A little goes a long way
- Really good value for money
Cons
- Some cats may not like the smell
| Quantity: | 300ml |

FAQs: Best cat litter for odour control
What are the different types of cat litter?
There are three different types of cat litter: wood and paper-based, silica, and clay. Wood and paper-based cat litter are the best budget options. However, unless otherwise stated, these litters will not clump. This means that there's the potential for unhygienic liquid to collect in the bottom of the tray. Some wood or paper-based cat litter, such as Tippaws Long-Lasting Clumping Litter, have been processed in such a way as to make them more effective at absorption and odour control.
Cats have a more acute sense of smell and may find scented litter a bit overwhelming. It's not natural to be inhaling perfumed products with chemical additives. Bear this in mind if you opt for a scented silica crystal cat litter. Also, sensitive paws may dislike the crunchy texture of silica. However, it's worth a try if you're looking for a low-maintenance cat litter that has excellent absorption.
The best clumping cat litter is made from Bentonite clay. This allows for the easy removal of urine-soaked litter with a scoop.
How does cat litter smell spread?
When litter gets caught in a cat's paws and spread around the house it's known as tracking. This is one way in which odour may be spread. Try putting a mat under the cat litter tray to catch stray litter. Or, you could switch to a litter that has larger granules. Additionally, your cat may be unintentionally spraying outside of the box. If you think this may be the case opt for a box with higher sides. To stop your cat from kicking up a stink make sure the litter tray is large enough; it should be one-and-a-half times their length. Finally, if the odour has suddenly changed do not hesitate to contact your vet in case of kidney or urinary tract disease. Kidney disease causes pets to urinate more.
What is clumping cat litter?
Clumping litter, made of clay, dries out cat faeces which helps keep the litter fresher for longer. Clumping litter allows for easy removal of liquid and solid waste. But your cat may naturally show a preference for another type of litter.
What else should I consider to improve the odour of my cat's litter tray?
If a rancid smell is coming from the litter tray itself then it needs a good clean. Cats do not want to dig in litter that's been soiled. It's a good idea to empty the litter tray and wash it with hot water and mild, unscented detergent every week. It's important to keep your cat's litter box clean for their hygiene and wellbeing.
Scoop clumping litter twice a day to remove lumps. Non-clumping litter should be checked once a day and changed every few days.
Avoid covered litter trays as these can make contained odours very unpleasant for your cat.
Plastic liners in a litter tray can be problematic as urine can seep under the liner and cause an unpleasant smell. Cats can also catch their claws on liners and unintentionally cause a mess.
A cat deodoriser should never replace basic good hygiene, but a deodoriser in granule, spray, bead or powder form can help improve unwanted smells.
Scented cat litter are also an option, though they may be irritating to some cats. There are unscented litters with deodorisers which neutralise odours and are a great option if your cat dislikes strong floral scents.
It can help to make sure the cat litter tray is being used as intended. Fill the tray with litter to a depth of 7cm. If there's too little litter your cat won't have enough depth to bury their waste. If there's too much litter they'll kick it out of the box.
