Why is there no mouse-flavored cat food?

Most types of cat food consist of leftovers from meat production for humans. However, since humans do not breed mice as food, mice would have to be bred and slaughtered specifically for cat food. The rodents are also very small and do not produce much meat. Therefore, from an economic point of view, mice in cat food are not worth it: the food would be very complex to produce – and therefore significantly more expensive for the cat owner than other flavors.
