Cats have a much stronger sense of smell than humans, with over 200 million smell receptors, making their sense of smell 14 times more sensitive than that of humans. This means that fragrances in cat litter can be overwhelming for cats, and some cats may be sensitive or allergic to scented litter. Scented cat litter can also affect a cat's ability to follow its natural instincts, causing unwanted stress and respiratory-related health issues. However, scented litter is designed to be safe for cats, and many cats use it with no problems. The decision to use scented or unscented cat litter depends on the preferences of the cat and its owner.

What You'll Learn
Cats' preferences for unscented litter
Cats have an incredibly sensitive sense of smell, with nearly 200 million odour receptors in their noses—their sense of smell is 14 to 40 times more sensitive than that of humans. This means that even lightly scented litter can be overwhelming and off-putting to them.
Unscented litter is made without additional scent agents and is often referred to as 'odorless' litter. However, it will still retain the smell of the materials it's made from, such as clay, wood, corn, or wheat. Some cats may not respond well to scented litter and may prefer the unscented option instead. This is because scented litter can be very toxic to cats and can trigger allergic reactions, breathing difficulties, and upper respiratory problems. Cats that are sensitive to the chemicals in scented litter often sneeze and have watery eyes.
In a 2011 study, Dr. Jacqueline Neilson examined the litter preferences of 35 neutered cats over a four-day period. The results showed a slight preference for unscented litter, with 16 cats preferring unscented, 12 preferring scented, and 7 showing no preference.
While scented litter can be effective at masking unpleasant litter box odours, it is important to consider the potential health risks to your cat. Cats prefer clean litter boxes, adequate size, and a sufficient number of litter boxes available (usually one more than the number of cats in the household).

Health risks of fragrance litter for cats
While scented litter is designed to be safe for cats, it can pose certain health risks. Cats have a much stronger sense of smell than humans, with over 200 million smell receptors, making their sense of smell 14 times more sensitive than that of humans. This means that fragrances that seem subtle to humans can be overwhelming for cats.
Some cats are more sensitive to scents than others, and scented litter can trigger allergic reactions and respiratory issues in these cats. Symptoms of sensitivity to scented litter include sneezing, coughing, and watery eyes. In addition, cats with a history of respiratory, skin, or urinary issues may be at risk of further health problems from inhaling fragrances and particles from scented litter. In rare cases, cats may also experience digestive issues if they ingest scented litter.
Scented litter can also affect a cat's natural instincts, causing unwanted stress and respiratory-related health issues. Feline Idiopathic Cystitis (FIC), the leading cause of house soiling in cats, has been linked to the stress caused by scented litter. FIC causes inflammation in the bladder, resulting in straining to urinate, frequent and painful urination, blood in the urine, and urinating outside the litter box.
While scented litter can help mask unpleasant litter smells, it is important to consider the potential health risks for cats. Cats generally show a slight preference for unscented litter, and it is recommended to choose a litter that aligns with your cat's preferences to encourage consistent litter box use. Natural, unscented litters that block odours without fragrances are a healthier option for cats.

The effectiveness of fragrance litter in odour control
Scented cat litter is designed to mask the odour of cat urine and faeces with fragrances. While scented litter is generally considered safe for cats, some cats may be sensitive to the chemicals in scented litter and experience allergic reactions, including sneezing, coughing, and watery eyes. Cats with respiratory issues, skin allergies, or urinary tract problems may be particularly vulnerable to the effects of scented litter.
The effectiveness of scented litter in odour control is supported by its ability to minimise the intensity of litter smells. The fragrances in scented litter can help to cover or absorb the odours of ammonia, faeces, and mould. However, some cats may find the fragrances too strong, leading them to explore alternative places to relieve themselves.
Unscented litter, on the other hand, does not contain added fragrances but may still include natural odour neutralisers such as baking soda, activated charcoal, or carbon. These ingredients can effectively absorb and neutralise odours without the need for artificial scents. Many cat owners find unscented litter with natural odour neutralisers highly effective in trapping odours.
The preference for scented or unscented litter may vary among cats, and some studies suggest a slight preference for unscented options. However, it is important to note that individual cats may have different scent preferences, and factors such as litter box cleanliness and medical issues can also influence their elimination habits.
To optimise odour control and encourage consistent litter box use, cat owners should consider their cat's specific needs and preferences. Proper litter box maintenance, including regular cleaning and replacement of litter, is crucial for maintaining a healthy and odour-free environment for both cats and their owners.

Natural alternatives to fragrance litter
Scented cat litter is generally safe for cats, but some cats may not respond well to it. It is designed to mask the odour of cat urine and faeces, but some cats may find the fragrances too strong and overwhelming. Cats have a much stronger sense of smell than humans, with over 200 million smell receptors, making them 14 times more sensitive to smells than us.
- Unscented litter with natural odour neutralizers such as baking soda or activated charcoal.
- Corn cob litter, which is made from corn kernels, is a natural option that clumps well, absorbs odours, and doesn't stick to fur. However, it may be messier as it can be kicked around and spread outside the tray.
- Coconut shell litter is a hypoallergenic option that can be used in gardens and flower beds afterward, making it a zero-waste product. However, it doesn't clump well due to its fine texture.
- Wheat litter is a natural, lightweight, and soft option with a pleasant smell and no artificial additives. It controls odour well but can be trailed around the house.
- Recycled paper cat litter is made from recycled paper products such as old newspapers or magazines. It is biodegradable and chemical-free but may not offer the best odour control for multi-cat households.
- Diatomaceous earth litter is made from fossilized algae and offers exceptional absorbency and natural flea control. It is a safe, chemical-free option for indoor cats.
- Pea fibre litter is a sustainable, biodegradable, and gentle option that provides natural odour control.
- Corn husk litter is a lightweight, compostable, and renewable option with excellent natural odour control.
When choosing a natural alternative to fragranced litter, it is important to consider your cat's preferences, the litter's absorbency and clumping ability, and its impact on the environment.

How to neutralise odours in unscented litter
While scented cat litter is designed to be safe for cats, it may not be suitable for cats with certain health issues. Cats with a history of respiratory, skin, or urinary issues may be at risk of further health problems from inhaling fragrances and particles from scented litter. Some cats may also have sensitivities, which can cause skin allergies and irritations.
Unscented litter is a better option for cats that are prone to these health issues. Some unscented litters contain natural odour neutralisers such as baking soda and activated charcoal. Many cat owners find these to be highly effective at trapping odours.
To neutralise odours in unscented litter, you can try the following:
- Use a litter additive, such as Hepper's Advanced Bio-Enzyme Cat Litter Deo, by sprinkling a bit into your cat's litter box.
- Mix a bit of baking soda into your cat's litter.
- Use a second litter box to reduce the rate at which waste piles up.
- Ensure your cat is not spraying outside of their litter box.
- Maintain good litter box hygiene.
- Use an unscented cat litter deodoriser, which works by neutralising odours.
- Choose a natural and biodegradable litter, which can help to reduce allergens.
- Try a low-dust litter, which can help to neutralise odours.
- Opt for a litter with added charcoal for extra odour protection.
