ACFA judges seem to be more "audience" related when it comes to talking about the cats or what is going on. They don't explain the workings of a show per say, but do explain about the breeds/qualities a lot more then some other associations. I showed a lot in ACFA.
CFA judges are hit or miss. This past show that Charlie was in - many of the judges talked to the audience about the breed. We were really impressed with one judge (Jan Rogers)(at least DH was since he's a "newbie"). As she judged the cats, she would tell a bit of history on them. She was pretty accurate too
She took Charlie out and first thing said "he may look wild, but he's 100% domestic" and then told how the breed came to be.
I was only in one TICA show, so I'm not familiar with the judges.
When I was a household pet judge I would talk to the audience about HHP's, their colors (correct
) and a little on how they were judged, what most judges look for etc. I always mentioned about how picky I am on grooming - especially on the longhairs
