I have a cat that will not eat out of the bowl. I have tried different bowls but he won't buge. He used to eat out of the bowl but has decided he doesn't like it anymore. He's about 3 and was feral but I socialized him and brought him inside. He has adjusted great and is a wonderful cat but about 6 months ago decided he only wanted his food on the floor. How can I get him interested in a bowl again?
