However, Wellness canned has NO grains, therefore there is no filler.
Looking at a can of Wellness I pulled from the cupboard, the first several
ingredients a Turkey, Chicken Liver, Chicken, Turkey Broth, Sweet
Potatoes, Carrots...
This leads me to believe Wellness is primarily meat.

Once you take out the water weight and compare the ingredients on a dry matter
basis, then how would the ingredient list read?
