When AB judges do their top 10, it depends more on how many males/females they have in the finals as far as if they can do it in one ring, or if they have too many males & not enough cages - they have to do 2 rounds of finals.
I should have looked to see what sex the cats were that finaled. At the last show they the finals in 2 parts in almost every ring. It was 8-10 first then 1-7.
