I thought I answered this yesterday but must have forgotten to hit "submit".
Anyway, it probably has more to do with the Wellness having more calories per ounce than most of the cheaper foods. Depending on the flavour, it's about 35-40 cal/oz, where as something like Fancy Feast is about 25-30 cal/oz.
Cheaper foods also tend to have more flavour enhancers in them like salt and "natural flavour" (which could even be MSG), so cats are inclined to eat more of them.
