The vast majority of the world's cats are non-pedigree - that is they do not belong to any particular breed, or they are cross bred or their parentage is unknown. The gene determining short hair is dominant, so most non-pedigree cats or moggies are short-haired, and of medium build and of course in a wide variety of colours.
Pedigree cats are selectively bred and display characteristics inherent to the breed. Each breed has its peculiarities, and in general, as "moggies" or cross-bred cats have the vigour, longevity and better overall health and of being hybrid, rather than specialized. The main feline features that vary are body type, eye colour, coat colour and length of coat. Some pedigree cats are natural breeds and many others are the result of careful breeding. Some examples of pedigree features are as follows:
- Persians: luxurious long hair and sweet open faces, gentle personality
- Burmese: lustrous satin-sheened coat, elegant body-line and curious intelligence
- Siamese: "pointing" colours, blue eyes, overall beauty, expressiveness
- Maine Coon: rugged appearance, large size, easygoing temperament
- Bengal: feral expression with small rounded ears, mischievous and boisterous personality
For each and every popular distinct pedigree breed there is at least one club or assocation who promote the well-being of the respective pedigree.
If you want a pedigree cat or kitten it is a good idea to buy from a reputable breeder. Many breeders of pedigree cats also show their cats and so breed towards producing a good healthy show cat with a view to keeping one or two themselves. It is more likely that they are bred for quality and temperament rather than pure financial gain.
