If you want to compare products you ought to compare products within

foods, which means they have passed AFFCO testing for growth and are
indeed "kitten" foods. Therefore the correct comparison would be to
compare one growth food to another.

Steve,

Chris and I went around and around on this topic recently. What
requirements are there for a product to pass the AAFCO (I assume that's
what you mean) feed trial for growth, other than having 8 kittens
consume the food for 10 weeks and show no significant nutritional
deficiency or stunting of growth? Theoretically speaking, if one were to
submit Science Diet Adult Maintenance to an AAFCO growth trial, would it
have any chance of passing?
