Silver vine, a plant that prompts rolling, rubbing and drooling much like catnip, works on more cats than catnip. BMC Veterinary Research tested 100 domestic cats: 79 responded to silver vine and 68 to catnip, detailed in the 100-cat head-to-head test.
Both trigger a short bout of sniffing, licking, rubbing and rolling. BMC Veterinary Research found silver-vine bouts scored as more intense than catnip bouts. For a buyer, that means wider reach plus stronger play, not a different kind of play.

Why does silver vine reach different cats?
Catnip acts mainly through nepetalactone, BMC Veterinary Research reports. Silver vine offers a mixed iridoid cocktail with nepetalactol, actinidine and related compounds. Powdered silver-vine fruit galls drew the most responses in the tests.
A single-compound cue misses some cats. A multi-compound cue can catch them. That mix helps explain why silver vine picks up many catnip-nonresponders.
How big is the advantage?
The 11-point gap sounds large. The same BMC team reports it did not reach statistical significance, at p equals 0.08. Blinded scores did find silver-vine responses significantly more intense, at p equals 0.02.
In plain terms, silver vine likely reaches more cats, but the study was too small to prove it. The stronger reaction is on firmer ground. Expect lively rolling rather than a guaranteed response.
What if your cat ignores catnip?
About 75 percent of cats that ignored catnip still responded to silver vine, PetMD reports in PetMD's silver-vine guide. That makes silver vine the best next try after catnip. Tatarian honeysuckle and valerian root scored lower in the same 100-cat test.
Try powdered fruit galls first: International Cat Care points to a 36-cat study where both plants increased scratcher use. That makes a treated scratcher a good redirect for couch scratching. Replace powder when scent fades.
- Dust a small pinch on a toy or scratcher for sniffing.
- Let the cat sniff, rub, roll and drool, then remove the toy.
- Reoffer another day after the brief habituation wears off.
Is rubbing safe, and why do cats do it?
Rubbing is not just play. Iwate, Nagoya and Liverpool researchers found rubbing coats fur with nepetalactol and sharply cuts mosquito landings, described in the Liverpool mosquito-defense report. The euphoric roll doubles as chemical defense. Sniffed use looks low-risk.
BMC Veterinary Research reports no adverse effects when sniffed, no addiction, and only brief habituation lasting minutes to hours. Neither plant was listed as poisonous by the ASPCA poison-control sources the authors consulted. Age still matters. Scientific American notes catnip sensitivity is inherited as an autosomal-dominant trait in roughly 50 to 70 percent of cats, and kittens under about 3 to 6 months often show no response. If a young kitten ignores both plants, wait a month and offer a fresh pinch on a scratcher.
