I did see the Wellness core canned , but I was just looking for the canned to provide a little variety with different flavors thats why I looked to the mixed cans.
The grain free canned by wellness may be the best choice....and I will just make them a sweet potato once in a while

( they love the sweetpotato and __ mixes by wellness)
actually they love just about any canned food so I don't think I will have a problem there
