Catnip & Silver vine - an amazing and power packed blend of our original Leaf & Flower catnip with organic ground Silver vine. A double whammy! If the catnip does not immediately tickle your cats fancy, the Silver vine will definitely do the trick. All four of Shady Cat's catnip blends are offered in a 1.25 oz. bag and .20 oz. glass tubes! Take your pick! You can't go wrong! How to use our catnip: we recommend that you keep your catnip stored in it's airtight bag. All your cat needs is a pinch. For maximum potency, rub the catnip between your fingers to release all the oils stored in the catnip. This blend is also great for multi cat households as not every cat is born with the gland that makes them respond to catnip! They should still respond to the silver vine in the blend though. I always let customers know that there is 5x the catnip in the black bag for just twice the price, so if they know their cat(s) love the product, go for the bag! Tubes are great for trying us out!
