The Supreme Cat Show is the world's largest cat show and is comparable to Crufts. It is organised every year by the world'soldest cat registry, the Governing Council of the Cat Fancy, or GCCF and takes place each November at the National Exhibiting Centre in Birmingham. Special awards of UK Champion and Supreme Champion can be gained at this show only and the cat winning Best In Show has the accolade of becoming the supreme exhibit.
The first Supreme Cat Show took place in 1976. Until then the GCCF itself did not organise cat shows, but licensed shows put on by the breed clubs and area clubs affiliated to it. The Supreme Cat Show was devised as a special show, which would only be open to cats which had won an open class at another championship show under GCCF rules, much in the same way that Crufts is only open to winning dogs. The show grew in size each year until it became big enough to be held at the NEC, which has been its home ever since.
Unlike most other shows the GCCF's Supreme Show has no miscellaneous or club classes; it does, however, have classes other shows do not have. There are four Adult Open classes for each championship status breed: Champion Male and Female classes for full Champions, the winners being eligible for Grand Challenge Certificates and Pre-Champion Male and Female classes for cats with one or two Certificates or who have qualified as kittens, competing for Challenge Certificates.
The same applies to the neuter classes which are split into Premier and Pre-Premier classes for males and females. Cats which are already Grand Champions do not compete in these classes but in special classes for Grand Champions, Imperial Grand Champions, UK Grand Champions and UK & Imperial Grand Champions only, the winner being eligible for a UK Grand Challenge Certificate. Grand Premiers, Imperial Grand Premiers, UK Grand Premiers and UK & Imperial Grand Premiers compete for a UK Grand Premier Certificate.
In these classes several breeds may compete together. UK Grand Certificates are only awarded at the Supreme Show; two such Certificates from different judges give the cat the title of UK Grand Champion/Premier or UK & Imperial Grand Champion/Premier if it has additionally gained that title. There is no Reserve UK Grand Challenge/Premier Certificate.
Best of Breed winners at the Supreme Show do not get certificates but compete against the other BOB winners in their section for Best of Variety.
The seven Best of Variety Adults (Persian, Semi-Longhair, British, Foreign, Burmese, Oriental and Siamese) compete for Supreme Adult, the seven kittens for Supreme Kitten and the seven neuters for Supreme Neuter. The Supreme Adult and the Neuter can add the coveted word 'Supreme' to their title.
Finally, the Supreme Adult, Supreme Kitten and Supreme Neuter compete against each other for the honour of being judged Supreme Exhibit.
