It is not a good habit for cats to be picky about food, but it is also because cats sometimes eat a kind of monotonous food, such as cat food, so they don't want to eat cat food when they eat something delicious. Otherwise, they should prepare more meat, feed fruits and vegetables, or some nutritious canned food. Then you should also pay attention to whether the cat is digesting. You can feed some honey water or old yogurt, or feed some meow stomach power to the cat. Pay attention to prepare clean water for the cat to drink, and then let the cat exercise.
