This is some really potent catnip! Our cats are really into catnip and when they tried this stuff they went crazy. As soon as we saw how much our cats were into it, we contacted the company about working together. Theyve worked out a special technique to grow an extra strong catnip. We think its a really great product, and our catastrophic cats agree! This catnip is grown in the US and is 100% Certified Organic.
