I would suggest that you do not go looking for yet another product.
I am presuming (maybe a mistake -?) that you are trying to provide a better "quality" food, that you did some searching and decided on the Wellness. If I'm wrong, don't hesitate to tell me!
Thing is, with changing over foods........do not expect it to be an instant yes/no decision.
Anytime you want to "switch" foods, do it ever-so-slowly.
Here's my experience with changing dry foods: Before the food recall, my five were getting Iams Original dry. Along came the recall disasterand, after a lot of research/reading/discussion, I decided I would "switch" to Orijen dry. By then I knew the necessity of s-l-o-w transitioning. Still, for the heck of it, I offered a few pieces of Orijen to each of them. Each one, in turn, took one sniff and walked away.
So, we moved into the transitioning - adding a few pieces in increasing amounts every day (and reducing the "old" in like amounts), so that over a period of 4-6 weeks they were getting 100% of the Orijen.
(Many dry products have "discarded restaurant cooking oils" sprayed on at the end of the extruding process...is it any wonder that cat's "just love them"?)
If you're satisfied with your choice of the product...then understand that it's not a taste-test contest...do the transitioning thing.
