This is not true
Eldorado's Bejeweled was last CERF'd July 2008, that test is valid for 12 months so she would not be expected to be tested again until July 2009.

Eldorado's Bejeweled is my girl Ruby and I was present at her CERF.
Eldorado's Barcelona (my girl Ruby's mom) crossed to the rainbow bridge last fall. I believe she was 11 years old.
