Johnson's started life in 1921 as Johnson Brothers, Poultry Specialists; manufacturing products aimed at the increasingly popular poultry breeding market. Johnson's expanded its product range to cater for both the popular cage bird and fledgling pet care market for dogs and cats. The range has now expanded to around 220 products ranging from Pigeon Tonic (where it all started) to the very latest in flea control - 4fleas tablets, the mainstay of the exclusive 4fleas range.
