I used to feed them Instinct but they have discontinued cat lines or only sell small bags of the stuff. I used to occasionally give them raw 2-3x a week as one of their 3/day feedings. I'll take a look at Tiki Cat.It mostly depends on where you live, just a general idea like country if outside the US or state if you're in the US. If you are in the US my suggestion would be Tiki Cat as they have several varieties that come in 10oz cans, it is more affordable and has comparable if not better ingredients than other LID canned food. The Chicken varieties have no gums, no fillers, and no plant based ingredients.
There's also commercial frozen raw food like Instinct (many pet stores carry it as does chewy), Darwin's, or Balanced Blends.
