I know that the folks (who, like you, are caring for CRF kitties) on the Helen's Yahoo Group
http://pets.groups.yahoo.com/group/feline-crf-info/ have started to compile an up-to-date list for all available foods - Helen has committed to adding a new page to her site
http://www.felinecrf.org/ once the info's in.
This was announced on the group over a month ago, so I'm sure much of the info will have been gathered by now. You might want to join her group and pose a pre-publication question...
I've been following your other thread...'tis not easy!
