My cat has eaten the same wet food (healthy, good stuff) for the past 3 years (he's about 4 or 5); the other day he suddenly refused to eat the food, though was meowing with hunger, and would only lick it. After 2 days of trying to give him the food (i would throw out the old, of course!), i bought different wet food that was recommended. He loved it! That was 2 days ago, and now he's not eating that food suddenly!! But still seeming very hungry, and will resort to his dry food if he's desperate, it seems. What does this mean????Thank you!!!!!!!!
