How about Hill's or Royal Canine wet food? I give my Maine Coon girl the kitten type of Hill's and RC wet food sometimes. There are no Maine Coon wet food or kitten food as I know of. If there were, I'd buy them as well
Remember to purchase the kitten type of a high quality food. Whiskas is a poor quality food, with no nutrition.
My cat does show a great interest in wet food in general too, but give her RC Kitten dry food daily, and sometimes I give her half the amount of dry food and then some high quality wet food (Hill's/Royal Canine).
