My cat just turned 1 yr 2 wks ago, and i have put him one purina one, with yogurt and salmonw/ tuna. He has been a little elisive lately- not his usual self. Also his poop is dark on the outside, but brown and the regular color on the inside of the stool. Should I be worried?

It may be a food allergy. I have a Boxer dog whom we suspect has an allergy to yogurt, but we haven't tested it out after the first time!
