This is Oliver. He is 15 years old. Last year he became super skinny despite eating us out of house and home, but he was eating jelly meat and biscuits. He was diagnosed as hyperthyroid, and one of the leading causes (apart from age) is soy in pet food. We switched to Jimbo's and now have one happy cat who has put on a good kilo. We go through almost 2 x 940gm containers in 10 days but at least he's keeping a bit of weight on and has his personality back!
