A show cat is one that has been judged to be close to the physical ideal for its breed standard at a cat show. Not all pedigreed cats are show cats, many are just pets but the ones with the best conformation and personality are often shown in associations such as the CFA and TICA in the US, the GCCF in the UK or the FiFe in the rest of Europe. Uncommonly, a prize-winning pedigreed show cat can be worth thousands of dollars but most are loved pets. In order to compare examples of breeds and improve stock, cat shows are held where judges evaluate the cats according to a breed standard. Pedigreed cats are often identified with microchip implants.

A cat show is a judged event where the owners of cats compete to win titles in various cat registering organizations by entering their cats to be judged after a breed standard. Both pedigreed and companion cats are admissible, although the rules differ from organization to organization. Cats are compared to a breed standard, and the owners of those judged to be closest to it are awarded a prize. Moggys are judged based on their temperament. Often, at the end of the year, all of the points accrued at various shows are added up and more national and regional titles are awarded.
