Scratch it! Catnip is a completely natural herb that in the wild, cats flock to form miles around. Drawn to bask in its sweet smell, it makes cats purr in delight and roll around in enjoyment! Catnip is used to attract cats to toys, scratching, and bedding products. Our brand of catnip is potent: a few spoonfuls are usually sufficient. It works great with scratch-it cat trees and scratchers.
