best place to find shows:-

GCCF - Welcome to the Governing Council of the Cat Fancy
TICA - Show Diary for TICA cat shows in the UK
FB - Felis Britannica - UK FIFe Cat Shows and Pedigree Registrations

They all operate in a different way and have different rules so best to read the info on each site first. Only FB do not allow pedigrees of any description to be shown as a Household Pet, both TICA and GCCF do.
