CBD Reduced Fear-Related Urination in Cats Exposed to Simulated Thunderstorms

After two weeks of CBD administration (4.0 mg/kg/day), cats exposed to a simulated thunderstorm showed significantly reduced fear-related urination compared to their initial test. No such improvement was seen in the placebo group receiving sunflower oil.

Randomized placebo-controlled study with 40 cats naive to the testing protocol. Cats were assigned to CBD (4.0 mg/kg/day for 2 weeks) or placebo (sunflower oil). Each group was exposed to a thunderstorm simulation test before and after the 2-week administration period. Fear-related urination was the primary behavioral outcome.

Noise phobia is one of the most common behavioral problems in companion animals. This small but controlled study adds to the growing evidence that CBD may have anxiolytic effects across species, using a practical and clinically relevant fear stimulus.

While this is a veterinary study, it contributes to the broader evidence base for CBD as an anxiolytic. Animal studies with naturally occurring fear behaviors (rather than artificially induced anxiety) may better reflect the real-world potential of CBD for anxiety management.

Small sample size. Only one behavioral measure (urination) was reported as significant. The study did not assess other fear behaviors like hiding, freezing, or vocalization in detail. Two weeks of administration makes it unclear whether shorter or longer treatment would differ.
