Jen,

Sorry to hear about your kitty's problems. I hope they can figure out what's going on. Poor Sterling.

I feed all my guys Wilderness Blue. It's all natural with no animal bi-products, or fillers. My cats coats are soft and shiny, and MooShoo has dropped a couple of pounds. His huge pouch has shrunk.

It's $33.00 for a big bag (smaller than Science Diet and Iams) but they don't eat as much. I also give them canned food to regulate their kidneys (adding water to it).

Please keep us posted on Sterling, okay?
