Medi-cal is an awesome food, and not more expensive than any other
premium brand. i've done the math. That said, it was recently bought out by royal canin and they changed the cat food somehow that my cats were on - I could tell it was different - and within a month their fur was dull and icky so I switched them to natural balance.
My dog (11m) is on eagle pac, but is shedding a lot, so i'm considering switching to medical or nutro. I had had my cats on eagle pac and found it dulled their fur, probably not enough essential fatty acids.
I had my other dog oh "N-R-G"
http://www.nrgpetproducts.com/ - it is dehydrated food and was an awesome food - but harder to get here. My dog went nuts for it.
