There was a time when cat show competitions were for purebred cats only, and the many happy owners of mixed-breed cats could not enter their pets in cat shows, no matter how beautiful and adorable they were.
That has changed, and now many cat shows award prizes in the Household Pet Competition. The strict rules applied when judging purebred cats are waived, except that mixed-breed cats entered in shows must be neutered and must not be declawed.
