Is there a difference between the small cans( 3 oz) and larger cans(5 oz)? I always buy the 3 oz cans because my male only eats a little wet food and it goes to waste; even though I divide one can for three feedings. I had to buy the next size up the 5 oz and noticed how moist it was, while the smaller cans are drier and my Zeus does not like it so much. Was this a fluke or are the larger cans a little moister? I really want to know because I will stop buying the smaller cans and buy the larger . My Zeus is lapping up this moister Innova. Thank you.
