If your cat is a picky eater, you can try to be firm and fast it for 2-3 meals. As long as you ensure your cat drinks plenty of water during this time, your cat's health will not suffer. After being fasted, the cat will be hungry and afraid of not having food, which will help it break its picky eating habit.
However, if the problem is that your cat doesn't like this brand of cat food, you can try switching to a different brand. If your cat has a sensitive stomach, it's recommended to keep some pet probiotics on hand and give them to your cat regularly. If your cat's picky eating is severe, and it refuses to eat or drink, or shows obvious signs of illness, it's best to take it to the vet.
