SynergyLabs® Xtreme Catnip. 100% Natural. More crazy fun... Than any other catnip! Guaranteed. Net Wt. 0.5 oz (14.2 grams). Strongest Catnip - guaranteed! Fun Facts: Catnip evokes different responses in cats - purring, licking, rolling, rubbing, jumping and running. The reaction usually lasts from 5 to 15 minutes. Kittens rarely respond to catnip. Catnip, added to food, will often coax a finicky cat to eat. Storing catnip in the freezer maximizes its freshness. Please recycle. 954-525-1133. www.synergylabs.com. © 2004 SynergyLabs®.
