Hi. I have a gorgeous 4 year old Maine coon male. He's flead and wormed regularly and I feed him a variation ( he gets bored easy) of iams, and Royal Canin Maine coon food. As well as wet food. He can take or leave the dry but wolfs down the wet and will cry for more all day. There's always food available in his bowl ( it's one where the food drops down when it's empty) but he's feeling a bit bony along his spine...I'm just wondering do I ditch the dry food completely and feed him the wet? Or introduce a raw food diet for him? Or is there anything I can give him to fatten him up?
