SmartyKat Catnip & Silvervine is an exciting blend of attractants guaranteed to entice your cat. Silvervine, a wild-growing herb foraged in the mountains of Japan and China, has a strong natural effect on cats - even on those that typically don't respond to catnip! Extensive testing led us to find the perfect mix. Our proprietary blend was created as an ideal alternative for finicky felines who need a little extra excitement. It's more potent than catnip and as pure as can be! Most cats respond to this blend with a burst of energetic activity followed by a calm mellow period. SmartyKat toys, beds and scratchers are designed to meet the needs of your cat: Exercise, Hunt, Stimulation, Interaction, Scratch and Comfort without forgetting about FUN! Kids and pets often share the same space in the home and will have access to each otheràtoys. That is why we design products to meet child safety standards; ensuring kids in the home are safe, whether they are two-footed or four-pawed! We utilize recycled and sustainable materials wherever possible. Please read all packaging instructions, warnings and cautions upon receipt. Packaging may contain small parts, discard after opening.
