I have two kitties one is 9weeks and another one is 10month....I'm giving them purina kitten chow dry food ....but yesterday I heard from my fiancé's brother that purina kitten chow is bad for cats...is that true?
The first ingredients are by-products, they don't specify the source either...i.e. Chicken by-products it just says Poultry which just gives them more opportunity to use random left over bits and also causes each bag to be inconsistent in content. Not that it would be any better if it were only Chicken by-products.
The next ingredients are rice, corn gluten mean and soy flour. This is mainly a bag of animal remnants that are deemed unfit for human consumption, could even be products from the 4 D's list and the rest is a bunch of carbohydrates that are of little benefit to your cat considering cats are carnivores. Actually, since there are 3 ingredients in a row that are carbs, they probably make up the majority of the food. Feeding a diet of only dry food can be unhealthy in itself, but this is a really bad food.
Check out some of the links in the health and nutrition section - there are tons of foods out there that are better than this one.
