With chicken meal (as in the Royal Canin)the water is already removed which is why I was thinking that the Pro Plan may have more corn in it.
The products are listed in a consistant order so that one can always find the nutrient most important in the selection and compare more easily -- at least to my understanding.
On a group list this morning we were discussing the topic of by-products and rendered foods which is something I have learned to have a rather biased slant on lately.
I live far too close to where someone has been bumping off about 50 or so of the local street ladies and the forensic team is now looking for DNA on clothing that is buried over a large site. They are very much playing down the fact that the 'gentleman' who lived on the property had a wood chipper and supplied a local rendering plant on a very regular basis, all during the time the women went missing.
Anyone who believes that "by-products" or "meal" are good for their pets should be reading the book by Ann Martin, (I think that is her name), called, "Food Pets Die For". There is a second book out that I haven't had time to look at, however, I did not hesitate to buy it as my boys mean a great deal to me.
One of the lists at Yahoo, (CATWELL), has several very learned individuals who have looked at many foods very carefully and Pro Plan has a definite thumbs down. Pro Pac is another matter, however Royal Canin is one other on their list that contains good quality food along with no toxic chemicals or poisonous material, that will eventually build up in your pet's system and cause serious health problems.
Eg.....the pea fiber aids digestion in Royal Canin that you have listed, and the chicken fat is the correct source of fat for feline carnivores. However, this is not recommended by this group, but Royal Canin Slim is.
Pro Plan Chicken & Rice has wheat products, and beef tallow, both of which I will not choose for my boys. One of them gets diarrhea every time he eats any beef product, let alone "tallow". You make candles and soap with that, not eat it.
As for food comparison's, there is a short list of popular canned and dry foods at the following website that might interest you:
Cat Food General Calculationshttp://www.sugarcats.net/sites/jmpeerson
and another site I seem to remember has useful information is the following:
Practical Feline Nutrition
Article on determining nutritional value of processed foods.
On the site for my own group, the files section is open to anyone with access to Yahoo and there are a couple of items in the "Files" section that are helpful in calculating calories, and percentages of nutrient content, etc.
Having said all that, what is counted as protein or other nutrients in "by-product" or "meal" may contain a lot of other items, other than the listed product on the pet food label.
