I have a new kitten named Phoenix. She was born April 1, 2010. Definitely born the right day that one. lol. Anyways right now she is eating purina kitten chow. Well actually just finished the bag today. It was given to me when I went and picked her up. my mother's 2 adult cats are on purina cat chow. However they were always eating Phoenix's food and Phoenix theirs. Is there a type of food that is safe for both? They are all nice size cats. Perfectly healthy. The only real nutritional needs are Phoenix's being a kitten.
