Not every cat responds to catnip, and some cats that ignore it may respond to silver vine. Neither is an essential part of cat care, and the safest introduction uses a small amount of a clearly labelled cat product under supervision.
Expect individual variation
Research reviewed by the University of Liverpool has examined silver vine as feline scent enrichment. Response rates in a study group do not predict what one cat will do. A cat may sniff, rub, roll, become playful or show little interest at all.
Introduce one product at a time
Choose a product sold for cats with a clear ingredient list and storage directions. Offer a small amount on a washable toy or scratcher in an open area. Do not mix several botanicals during the first trial, because you will not know which one prompted the response.
Supervise and remove after the session
Prevent the cat from eating packaging, sticks or large quantities of loose plant material. End the session if play becomes frantic, cats compete, or the cat shows coughing, vomiting, skin irritation or distress. Contact a vet about any persistent or severe sign.
Use scent as an optional introduction
A little catnip or silver vine may encourage investigation of a scratcher, but never force contact. The Scratch Central is one current sisal option; check the product instructions before adding anything to its surface and leave an unscented scratcher available.
