1. Buy about half a catty of small fish from the market or supermarket and dry them. This dried fish is an untreated dried fish, not the kind of snack dried fish that has been made.

2. Prepare a pot, treat the dried fish briefly, then put it in the pot, add water and bring to a boil. If there is no pot to boil, soak the dried fish in hot water.

3. After the dried fish in the pot boil, salvage the dried fish and drain. Pour the water out of the pot, change the water for two or three times and boil the salty taste of the dried small fish. If you soak in hot water, you should also change the water several times.

4. After the above steps of boiling to remove the salty taste are completed, fish the dried fish and drain the water. Stir-fry the dried fish slowly with a small fire in an iron pan. You can also use the method of sun drying.

5. If there is an oven at home, put the dried fish in the oven to dry.

6. Put the dried small fish into a bag, put a desiccant on it and store it in a cool and dry place. Take it out for the cat when it eats.
