I once heard a quote: "Don't confuse me with facts - I've already made up my mind."
Should I go with Cat Chow Naturals or Purina ONE SmartBlend Indoor Advantage dry food
Neither. Cats don't eat grain, except a tiny amt that might be in a mouse, bird.
Count the number of grain & plant matter ingredients those have. You should also research the % of total calories coming from carbs & the % of carbs on a dry matter basis (DM). I'll assure you, they're VERY high in carbs, which very often causes problems for cats.
If you added up all the non-meat ingred (supplying protein, fat, carbs) , it often outweighs the total meat. It even has cellulose. Do you think cats eat much ground paper?
Here's a test: Put separate bowls of meat, corn, corn meal, wheat, soybeans, cellulose, etc. out for a cat. See if they eat any except the meat.
Cattle feed mfgs "fooled" cows - strict herbivores - into eating animal protein by mixing it in feed & flavoring it. Look where that lead.
You don't feed iguanas or parrots hamburger.
If you don't mind the significant increased risk in cats - feeding dry food - of diabetes, FLUTD, UTIs, CRF, over weight & many more serious problems, OK.
Several are easily fatal.
Diabetes is "epidemic" in cats now. Vets says FLUTD / UTIs are two of the most frequent feline problems they see. Many vets attribut it to dry food, high carbs, low water.
Just do research - on vet articles. Start here: http://www.catinfo.org/
. There's a wealth of info. There are many other good sites by vets, explaining cat nutrition & they're strict carnivores.
Fairly expensive dry almost killed 2 of our cats - it cost us a fortune in vet bills. I know many owners it did kill their cats.
There's nothing wrong w/ by products - cats eat the whole animal they catch. Felines often start eating the internal organs 1st (ever watch nature shows or a house cat eat a mouse)? The internal organs have more calories & some nutrients not found in muscle meat - that's why bears eat the fish entrails & leave the rest, when they're trying to fatten up.
Poultry / meat or by product MEAL
... is a different story. It's been processed to death (rendered) - several times & much of the nutrients, incl. essential amino acids have been destroyed. The "meal" (pulp) is what's left.
If canned food contains meat "meal," it should be way down the ingredient list.
2ketzels comment on an article about chicken being bad, may have to do w/ the poor quality (of any meat) that some mfgs use in pet food.
Maybe chicken that's full of antibiotics or pumped full of phosphates (containing phosphorous). Research that practice by many chicken producers.
But birds would be a natural part of wild cats' diets. They wouldn't eat fish in the wild - except for one "fishing cat" species, AFAIK. They shouldn't be fed much fish, as it's too high in magnesium & phosphorous - both can cause serious problems if much higher levels than wild cats' normal diet. Not to mention mercury.
We just rescued a cat that'd been fed dry, began having kidney failure & was abandoned to die by owners. She couldn't walk, eat - hardly make a sound. We force fed her over 3 weeks - quality canned food & pureed meat + vitamins + water. She now eats LOTS, runs - fast, jumps, plays, loves laps. One of the most gentle, affectionate cats.
