You referenced an article from Dr Scott Brown, VMD, PhD, ACVIM from the
University of Georgia.  He has written many on this topic.  Yes, the
fish oils have the omega 3 fatty acids (EPA and DHA) that help to
reduce inflammation.  In the kidneys, fish oils lower the amount of
the eicosanoids (prostaglandin E2 and thromboxane A2), which reduces
glomerular pressure and slows the progression of chronic kidney disease.
Omega 6 fatty acids (vegetable oils) increase the production of the
eicosanoids, increase glomerular hypertension, and speed up the
progression to end-stage kidney failure (death).  That is one of the
reasons Iams/Eukanuba kitten, Totally Ferret, and Marshall's ferret
food all have fish oil in them.
 
Hope that helps,
Jerry Murray, DVM
