Respiratory Issues & Cat Litter
Some cat owners consider dust and fragrances in litter when their cats have respiratory concerns. We are not vets—this is what we've learned from research, not medical advice.
Understanding Feline Respiratory Issues
Cats have sensitive respiratory systems that can be easily irritated by airborne particles and chemical compounds. Feline asthma alone affects an estimated 1-5% of cats[1], and many more experience respiratory sensitivities that may not rise to the level of a clinical diagnosis.
The litter box is one of the most significant sources of airborne irritants in a cat's environment. Every time a cat digs, covers their waste, or simply steps into the box, particles become airborne. For cats with respiratory sensitivities, this daily exposure can lead to chronic inflammation and worsening symptoms.
What Some Owners Report Noticing
Note: These are observations reported by cat owners, not diagnostic criteria. Only a veterinarian can properly diagnose respiratory issues.
- Sneezing — Some owners notice increased sneezing around certain litter types
- Coughing or wheezing — Some cats make sounds that concerned owners describe this way
- Changes in breathing patterns — Some owners notice their cats breathing differently
- Watery or irritated eyes — Some owners report this alongside other observations
- Behavior changes after litter box use — Some cats seem to avoid dusty litters
Any of these observations warrant a call to your veterinarian.
Why Litter Choice Matters
Two primary factors in cat litter can affect respiratory health:
1. Dust
Many clay-based litters produce fine silica dust that becomes airborne during use. When inhaled, these particles can irritate the airways and, with chronic exposure, may contribute to respiratory disease[2]. Even "low dust" formulas may produce enough particles to affect sensitive cats.
2. Fragrances and Chemicals
Scented litters contain volatile organic compounds (VOCs) that can trigger asthmatic reactions in sensitive cats. These artificial fragrances are among the most common triggers for feline respiratory issues[3]. Even "fresh scent" or "light fragrance" products contain enough chemicals to cause problems.
What Some Cat Owners Choose (Our Opinions)
These are our personal preferences based on research, not professional recommendations. Every cat is different—discuss litter changes with your vet.

Commonly Avoided by Concerned Owners
Recommended: Activated Carbon for Odor Control
If you're concerned about odor but want to avoid fragrances, activated carbon is an excellent solution. Unlike chemical fragrances that mask odors and irritate airways, activated carbon physically adsorbs odor molecules, eliminating them without releasing any irritants.
Purrify uses premium activated carbon technology specifically designed for cat litter odor control. It's fragrance-free, dust-free, and safe for cats with respiratory sensitivities. Learn more about how it works →
Additional Tips for Respiratory Health
- Ventilate the litter area — Good airflow helps disperse particles
- Don't place litter boxes in enclosed spaces — This concentrates airborne irritants
- Pour litter slowly — Reduces dust cloud when refilling
- Consider a covered box with filter — Can reduce particle escape
- Clean regularly — Ammonia from urine can also irritate airways
- Monitor air quality — An air purifier near the litter area can help
When to Contact Your Veterinarian
Please contact your veterinarian if you have ANY concerns about your cat's breathing or health. We are not qualified to tell you when something is or isn't serious. Cats are good at hiding illness, so err on the side of caution.
Only your veterinarian can properly diagnose respiratory conditions and recommend appropriate treatment. Environmental changes like switching litter should be discussed with your vet, especially if your cat has health issues.
