A Japanese study found that domestic cats show limited interest in catnip compared with a stronger response to silver-vine [1, 2].
This discovery challenges the common perception of catnip as the primary attractant for feline behavior. Understanding the relative potency of these plants helps researchers identify why cats are drawn to specific chemical compounds and how those preferences evolve over time.
The research focused on the effects of nepetalactone, the active compound in catnip, and compared it to the properties of silver-vine, also known as matatabi [1, 2]. The findings indicate that the attraction to these plants is not uniform across all cats. Specifically, the study noted that kittens show little to no reaction to these stimulants until they reach sexual maturity [2].
Researchers in Japan conducted the study to assess the relative potency of these plants and to understand the biological drivers behind the attraction [1, 2]. While catnip is widely marketed as a universal feline stimulant, the data suggests that silver-vine may be a more powerful trigger for the behavioral responses associated with these plants.
The study suggests that the chemical makeup of silver-vine interacts more effectively with the feline olfactory system than the nepetalactone found in catnip [1, 2]. This difference in response may explain why some cats appear indifferent to catnip while remaining highly reactive to other plant-based stimulants.
“Cats show limited interest in catnip compared with a stronger response to silver-vine.”
These findings suggest that the feline pet industry's reliance on catnip as the gold standard for stimulation may be based on incomplete data. By identifying silver-vine as a more potent attractant, scientists can better understand the olfactory receptors of domestic cats and the hormonal shifts that trigger these responses during the transition from kittenhood to adulthood.
