Anonymous meats are inexpensive low-quality ingredients that can come from practically any animal. These type of ingredients are often used to produce very inexpensive cat foods.

In general, we prefer ingredients which specify the animal source used to derive the ingredient. For example, ingredients such as duck fat are much better than animal fat or poultry fat.
