My kitties eat the B.G. chicken dry food and love it a whole lot. Haven't tried the B.G. canned varieties--my critters like Merrick, Prairie, Eagle Pack, and Pinnacle canned (but only certain flavors, of course ).

Kiri, whose kidneys failed entirely two years ago, eats the canned foods mentioned above (and even though she's pretty much toothless, she sneaks a bite of the dry food now and then). Her kidney levels have been pretty much normal.
