At Greycoat Research, we often meet guardians who have done everything right—managing diet, supplements, and hydration—
yet still face the frustration of stagnant or worsening kidney values.
When this happens, it may be time to look beyond nutrition.
One often-overlooked factor in feline CKD care is the indoor environment, especially fragrance exposure.
Fragrances from diffusers, scented candles, air fresheners, and even certain flowers may seem harmless to humans.
But for cats with compromised kidney function, these can become hidden sources of toxic stress.
We’ve even seen real-world cases where a cat’s kidney values worsened after a diffuser was placed near their living space—especially in humid homes where air circulation is limited.
Because CKD reduces a cat’s ability to eliminate toxins efficiently, even mild irritants can accumulate and lead to added strain on the liver and kidneys.
❗3 Fragrance-Related Risks to Avoid in CKD Cats
1. Personal Use of Diffusers, Perfumes, and Scented Lotions
Many of these contain concentrated chemical compounds.
Cats can be exposed through skin contact or by inhaling airborne particles, which may strain their kidneys and respiratory system.
Try to avoid them—or at least keep your cat away from scented areas.
2. Scented Cat Litter
While it may reduce odor for humans, scented litter poses a risk for cats with CKD.
Fragrance particles can be inhaled or ingested during grooming, placing additional burden on detox systems.
Switch to unscented or low-irritant litter for safer daily use.
3. “Natural” Scents from Plants or Oils
Scents from hinoki, eucalyptus, lavender, clove, and similar botanicals may feel calming to us,
but they contain compounds that cats cannot break down due to their limited liver enzymes.
Even low-dose, continuous exposure can accumulate and potentially harm the kidneys.
Creating a Safer Home for Your CKD Cat
At Greycoat Research, we believe kidney support goes beyond supplements.
By reducing fragrance exposure in your cat’s environment,
you help ease the toxic load on their kidneys—and support long-term wellness.
