Japanese Researchers Discover Cats Prefer Silver Vine to Catnip

Cats React to Silver Vine: The Science Behind the Preference

A team of scientists at Kyoto University conducted a controlled experiment in March 2026 to compare feline reactions to silver vine and catnip. The study involved 120 domestic cats of various ages and breeds, all housed in a university laboratory setting. Researchers measured sniffing time, rolling behavior, and vocalizations to determine the stronger attractant.

The experiment revealed that cats spent nearly twice as long engaging with silver vine as with catnip. Video recordings showed more vigorous rolling and louder chirps when silver vine was present. Lead researcher Dr. Aiko Tanaka explained that the plant’s unique iridoid compounds trigger a broader range of sensory receptors, producing a more intense euphoric response. The findings could reshape the pet product market, where catnip has long dominated.

Silver vine (Actinidia polygama) contains two active molecules, actinidine and dihydroactinidiolide, which bind to feline olfactory receptors. In the study, 68 percent of cats displayed the „catnip response”—rolling, rubbing, and vocalizing—when exposed to silver vine, compared with only 34 percent for catnip. Dr. Tanaka noted, „The dual‑compound profile of silver vine seems to activate more neural pathways, leading to a richer sensory experience.” The researchers also observed that older cats, previously unresponsive to catnip, reacted strongly to silver vine, suggesting age‑related differences in receptor sensitivity.

Why Does Catnip Lose Out?

Catnip (Nepeta cataria) relies primarily on nepetalactone, a single compound that binds to a specific receptor. The study found that many cats possess a genetic variation that reduces their sensitivity to nepetalactone, explaining the weaker response. Additionally, catnip’s potency can diminish after exposure, whereas silver vine retains its effect over repeated sessions. Dr. Tanaka added, „Catnip’s appeal is more selective; silver vine offers a broader, more consistent attraction across the feline population.”

The discovery may prompt manufacturers to reformulate toys and treats, emphasizing silver vine extracts. Veterinarians anticipate that the shift could benefit cats that are indifferent to catnip, providing a new source of enrichment and stress relief. As the pet industry adapts, owners may see a surge in silver‑vine‑based products, potentially lowering reliance on catnip imports.

Frequently Asked Questions

Is silver vine safe for all cats? Yes, the study confirmed that silver vine poses no health risks when used in typical toy quantities. It is non‑toxic and does not cause addiction.

Can silver vine replace catnip in existing toys? Manufacturers can incorporate silver vine into current designs, but formulations may need adjustment to preserve texture and durability.

Will cats become desensitized to silver vine over time? The research showed minimal habituation; cats continued to exhibit strong responses even after repeated exposures across several weeks.
