I rescued a cat about 3 years ago. He had belonged to an old lady who apparently spoiled him rotten. He has begged for people food and refused to eat most of what I feed him. However, I was most surprised that when I fed him New Balance the past two days, he has eaten with gusto and has finished off the can by the end of the day. I am very pleased but hope there is not some hidden ingredient he likes that isn't good for him. I got it at Walmart and understand it is new there. He does not like Friskies up the ladder to Purina Pro Plan. Any ideas?
