There are discussions on this topic here http://itchmoforums.com/index.php?topic=411.0
There have also been posts on Itchmo about Fancy Feast...there are people who have been "bashing" FF for some time...IMO without justification, but citing rumour and blog gossip. One individual is blaming FF for renal failure, while ignoring that they also fed the cat with an Iams weight control food - which HAS been linked to this condition. I'm no promoter of FF but, since the recall I have become educated about cat foods and, while I used FF for the past 3 years, I am now changing to a food with better quality ingredients. FF is widely used, is affordable and is extremely popular among cats.
In the thread I referenced for you, people have suggested that this site http://felinecrf.org/
is of great help in dealing with renal failure cats. I would strongly agree. Now, the people who run that site also run an on-line support group for pet parents deling with a sick cat - that
is truly amazing, and the people in that discussion/support group often know more than many Vets! Those people frequently recommend Fancy Feast
for cats who can't/won't eat other foods. Surely, if there were a problem with FF, it would NOT be RECOMMENDED by them!!!!!!!
