About 27 years ago, I took in a Maine Coon, abandoned cat. I had the same problem with him. The only cat food he woud eat was canned liver and chicken. I remember spending many dollars in sampling all the cat foods available then. What he did eat was all the birds, lizards, and ground squirrels he could find. What a mess, when he brought them into the house. One day he brought in a quail, and the bird got lose in the house, The cat (I called Tom), was chasing the injured bird all over the house and with feathers flying everywhere. Finally I got the bird outside, without Tom's acceptance! But I had a mess to clean up.
