Four Paws Super Catnip Crazy Pants are constructed of highly durable polyester and printed with a BOLD and bright pattern. The pants themselves have been sprinkled with catnip (within the lining) and have incorporated a crinkly material to drive cats wild! They measure a monstrous 37? at the waist and the pants are 25? long-the ?legs? or the actual ?tunnels? are 14.5? long.
