At Hagen, we recognize the specific requirements of various bird species and work to develop products that best fulfill their individual needs. Vision re-invented bird cages to respond to the real needs of birds and their owners. Living World remains dedicated to providing quality bird food, supplements, cages, toys and accessories. Tropimix and Tropican lead the way in premium nutrition thanks to years of devoted research and development by our very own H.A.R.I. (Hagen Avicultural Research Institute). Find HARI on Facebook.
