"I have two cats who've tried a few different premium wet foods, including Wellness and Natural Balance which they liked ok. But they really loved the tuna and sardine Avoderm Select Cuts (the chicken, not-so-much). You can see easily identifiable chunks of tuna, sardine, shrimp, crab etc. in a fish broth and that's it. No vegetables or grains, only protein and some necessary supplements.
People comment on their coats which are really shiny and smooth from the omega-3. I'm not sure that this should be 100% part of daily diet though. My cats are eat mostly chicken (about 70%) and the rest is Avoderm seafood."
