OK so I work at a pet supplies store and a lady came in and showed me that all foods must listed this:
Some foods say that it was made to meet the requirements but doesnt say that it was tested by feeding it to cats (in this case). Obviously if it was tested then it is better than something that is just supposed to meet the requirements.
Also the other thing is that some foods say that it was fortified for all life stages. When something is made for all life stages then it is a kitten (again in this case) food becuase thats what the compainies are required to make at minimum. I found this on adult cat food!!
So its not really an adult food but a kitten food with an adult label!!
Some the food comapinies are doing this because its cheaper than making a food for each and every life stage. But, like on the food I showed above, there are a few types of food out there that are made for all life stages and tested before coming on market.
Just wanted to share. After talking with this lady I decided to switch my pet food to something that is better quality.
(And to avoid confusion, most kitten (again in this case) food will say for all life stages because you also feed it to help put weight on an adult cat or to a lactating/pregnant adult female. The adult and senior should, however, say for adult or for senior.)
