Cat food can be mixed, but the mixing ratio needs to be carefully considered. When switching cat food, it's generally best to mix the old and new food gradually. Secondly, it's recommended to primarily feed one type of cat food, choosing one that's suitable for your cat. Mixing dry and wet food can also increase palatability. Mixing different types of cat food in appropriate proportions can also provide a more comprehensive diet for your cat. It can also help develop their digestive system, but it's advisable not to mix too many types, as this may cause gastrointestinal upset or diarrhea. 
Precautions for mixing cat food:
1. When switching between old and new cat food, add the new food gradually. It's generally recommended to wait at least a week before changing your cat's food, gradually increasing the amount of new food and decreasing the amount of old food each day. This is a mixed cat food, adjusted according to your cat's digestive system. It's generally not recommended to frequently change your cat's food, as their digestive system and taste have already adapted to the old food. As long as the old food is nutritionally sufficient, don't change it easily.
2. When mixing dry and wet food, it's important to distinguish between main food and supplementary food. Some cats don't like eating completely dry food and need a little canned cat food to stimulate their appetite. Therefore, it's necessary to pay attention to whether the cat's main food is dry or wet food and determine the appropriate mixing ratio. Some cats are very picky and only like canned cat food, which is also not advisable.
