Four Paws Super Catnip Crazy Cat 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.
