Silver vine - This brown, crumbly powder has to be the most mysterious catnip alternative, but it is the most popular treat cats just can't get enough of! Silver vine is a small fruit grown in Asia (cousin to the Kiwi fruit! How odd!) that is the Eastern equivalent to catnip. The powder is noted in various studies to have a higher effectiveness rate on cats than catnip anywhere from 75-90%, whereas catnip’s effectiveness rate is somewhere between 65-85%. We also offer this exact size of Silver vine as part of our Superb Sampler Set. And we also offer a much larger size for a fantastic value once you realize your cat absolutely loves Silver vine!
