I'm transitioning our cats to homemade cat food designed for carnivores(link above)
A grinder and ice trays are helpful as well as small containers with lids https://www.amazon.com/gp/product/B07BWH7LR6/ref=ppx_yo_dt_b_asin_title_o04_s01?ie=UTF8&psc=1
Partially cooking it can transition cats that have never eaten raw food before. This is my favorite site for homemade raw cat food: https://hare-today.com/raw_food_for_cats
