The Rex breed can be traced back as far as 1930 or 1931. The first German Rex was discovered shortly after World War II by Dr. R. Scheuer-Karpin who spotted a female cat wandering around near a hospital in East Berlin. The German Rex bears an uncanny resemblance to the British Cornish Rex, but they are usually a bit heavier and have a slight curl in their whiskers. They are friendly cats and can easily learn acrobatic tricks. Fur density range from thin to thick. Fewer breeds are in existence these days.
