Remember freeze-dried raw food is not intended to be a complete and balanced diet. It is for supplemental feeding and snacks. Give it to Sammie as an additive to encourage eating the new wet food if you need to.
That isn't true. Many brands of freeze dried raw are complete balanced meals. Some brands are Stella and Chewy, Vital Essentials, Nature's Variety, Feline Natural, and Primal. Definitely read the label and choose the meal which is typically kibble shaped or nugget shaped, not the treats or toppers.
