I have a 25 pound ragamuffin boy Wolfy. Ragamuffins as a breed can be big sorta like maine coons. He just turned 4 so is fully grown. His appetite is insatiable he wolfs down his bowl then goes after the food our other cat is eating.. He is eating canned wellness right now. I am concerned cause he is still putting on weight and really should be around 20 pounds. I am thinking of switching him to raw and just wondering if it might help with the weight problem.
