TL;DR
Japanese researchers found that cats prefer silver vine over catnip, even though catnip contains higher levels of the active compound. This challenges assumptions about what attracts cats and may impact pet product development.
Japanese researchers have confirmed that cats prefer silver vine over catnip, despite the latter containing higher concentrations of the active compound that attracts them, a finding that could influence how pet products are developed and understood.
The study, conducted by scientists at Iwate University, involved offering cats a choice between silver vine and catnip. Results showed a clear preference for silver vine, with cats exhibiting more vigorous reactions to it. Interestingly, chemical analysis revealed that catnip contained a higher concentration of nepetalactone, the compound traditionally associated with feline attraction, than silver vine.
According to lead researcher Dr. Ayaka Fukushima, the findings suggest that factors beyond just compound concentration influence feline responses. “Cats seem to respond more strongly to silver vine despite its lower levels of nepetalactone, indicating other compounds or sensory mechanisms may be involved,” she said.
Why It Matters
This discovery matters because it challenges long-held assumptions in pet product marketing and development, which have often focused on the presence of nepetalactone as the key attractant. Understanding that cats prefer silver vine despite lower levels of this compound could lead to more effective enrichment products and better insights into feline sensory biology.

Background
While catnip has been widely used in toys and treats for decades, silver vine has gained popularity in recent years, especially in Japan and Asia. Previous anecdotal reports suggested cats responded strongly to silver vine, but scientific evidence was limited. This study provides the first controlled comparison, confirming cats’ stronger preference for silver vine and prompting further research into the mechanisms behind feline scent attraction.

“This study could change how we think about feline enrichment and the development of toys or treats. It shows there’s more to attraction than just chemical concentration.”

What’s Next
Researchers plan to investigate the specific compounds in silver vine that elicit stronger responses and explore how these findings can inform the development of new feline enrichment products. Additional studies may also examine variations across different cat breeds and environments.

Key Questions
Why do cats prefer silver vine over catnip if catnip has more of the active compound?
Scientists believe other compounds in silver vine or different sensory mechanisms may be responsible for the stronger response, beyond just the concentration of nepetalactone.
Is silver vine safe for cats?
Yes, silver vine is generally considered safe for cats when used appropriately in toys or treats, but owners should monitor reactions and consult a veterinarian if unsure.
Will this change how pet products are made?
Potentially. The findings could lead to the development of new enrichment products that leverage silver vine’s stronger appeal, improving feline engagement and well-being.
Are all cats equally responsive to silver vine?
No, individual responses can vary. Further research is needed to understand breed or personality differences in scent preferences.
