Silver vine is *Actinidia polygama*, a cold-hardy climbing plant also called matatabi that triggers rolling, rubbing, and playful hyperactivity in many cats. For cat owners, it offers an effective olfactory toy that often works when catnip does not. It comes as dried leaves, stems, and especially fruit galls sold as sticks, powder, and toys. A typical session brings chin and cheek rubbing, licking, drooling, and rolling for 5–30 minutes.

What triggers the response?
The effect comes from iridoids dominated by nepetalactol plus actinidine and related compounds. Those chemicals prompt rolling, chin and cheek rubbing, drooling, licking, and hyperactivity. Most sessions last 5–30 minutes per exposure.
Rubbing also spreads nepetalactol onto fur, where it repels mosquitoes. Researchers describe licking, chewing, and rolling as chemical pest defense, not only play. That helps explain why the behavior looks so focused and physical.
How does it compare with catnip?
In controlled tests, 79% of domestic cats responded to silver vine versus 68% to catnip, 53% to Tatarian honeysuckle, and 47% to valerian root, according to a summary from EveryCat Health Foundation. Responses to silver vine were also more intense.
The gap is largest for cats that ignore catnip. Almost 75% of those cats still responded to silver vine, according to reporting from International Cat Care. For owners of a catnip non-responder, silver vine is the best next option to try.
Which form is strongest?
Potency varies by plant part. Fruit galls and powder are strongest, while stems are weakest, according to research in BMC Biology. Only about 20% of cats responded to stem material in one study.
Choose powder, gall pieces, or toys filled with gall powder for the strongest effect. Sticks can still entertain cats that like to chew and rub. If one form fails, try a gall-based powder before giving up.
How do you offer it safely?
Safety testing found no addiction or stress hallmarks. Cats self-terminated during four-hour access, response bouts had a median of about 90 seconds, cortisol did not rise, and liver and kidney markers stayed normal after multi-year exposure.
Offer a small amount at one time and supervise the session. Practical use looks like this: Overexposure can cause brief overstimulation or mild digestive upset, so stop if play turns frantic or chewing becomes heavy.
- offer one stick or a small pinch of powder
- remove chewed sticks before pieces break off
- pause 20–30 minutes after effects fade before offering more
