My fiancee moved in last October with her two cats. When they moved in, they both ate a reasonable amount of food. They would share out of one bowl and, again, eat a good amount. Nowadays, Max, the oldest one, just eats, eats and eats. Meanwhile, this hurts our other cat, Batman, because he eats less, but doesn't complain.\n \nWhy is this happening? How do we solve this issue? Any help is greatly appreciated.
