Silver vine - This fine brown 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- up to 95%, whereas catnip’s effectiveness rate is somewhere between 65-85%. My "kitty contraband" is POWERFUL!
