What is the common way to distinguish the Manx cat because of the cat body-type mutation?
Cat body-type mutation Cats, like all living organisms, occasionally have mutations that affect their body type. Sometimes, these cat body-type mutations are striking enough that humans select for and perpetuate them. This is not always in the best interests of the cat, as many of these mutations are harmful; some are even lethal in their homozygous form.
European Shorthair The European Shorthair, also called the European or in WCF Celtic Shorthair, is a breed originating in Europe. The term has also been used as an elaborate way of referring to common domestic cats of Europe, causing some confusion as the pedigree cats of this breed also should resemble the typical domestic cats of Europe. This role was held until the beginning of the 20th century by the British Shorthair, even though stockier than the majority of common European cats, until 1949 when the European Shorthair was recognized by the Fédération internationale féline (FIFe). The oldest known European Shorthair registered in FIFe was born in 1940, as the origin of the European Shorthair predates the formation of FIFe in 1949. Breed standards describing the European Shorthair as an established breed can be found in different cat books from the 1930ies.
