Soak the cat food in water. If the cat food particles are scattered, it means that the cat food is of average quality, and the qualified pet food will remain in its original state. Then look at the color of the soaked water. The yellow color is due to the precipitation of food oil. This is a normal phenomenon. If it is dark or even black, it means that the pet food contains more impurities and is not good quality cat food.

The owner needs to pay attention that under the same volume, the meat The density of starch is higher than that of starch, so there will be a decrease in sedimentation. Therefore, if there is a lot of sediment, it means that the quality of cat food is high, and if there is less sediment, it means that the quality of cat food is poor. Because cats are carnivores, it is necessary to have high meat content in cat food.
