Reasons why cats are picky eaters:
1. If a cat is severely deficient in zinc gluconate, it may cause the cat to become picky about food. In this case, it is recommended to supplement the cat with zinc.
2. Cats that eat the same brand of cat food for a long time may become picky eaters. It is recommended to feed your cat mixed food, switching brands periodically. Note: Mixing food doesn't mean mixing all the cat food together; it means changing brands periodically. Mixing different brands together can cause over-absorption and indigestion in cats.

How to prevent cats from being picky eaters:
1. Develop good eating habits
Harden your heart and don't share the hardships with your cat, because once a cat has tasted human food, it will resolutely leave the embrace of cat food. As the saying goes, it's easy to go from frugality to extravagance, but difficult to go from extravagance to frugality. Developing good eating habits and sticking to them is the best way to prevent your cat from being a picky eater. Using nutritional supplements can also improve a cat's picky eating habits. In summer, most cats will have less interest in food. This is not true pickiness, but rather that the cat needs to control its calorie intake. When the temperature rises, cats need less calories, so they eat less in hot weather, which is a common phenomenon. In summer, to improve a cat's appetite, you can give them a little bit of canned cat food.
2. Feed small amounts frequently.
Kittens under 3 months old can be fed four or even five times a day. Kittens aged 3 to 8 months can be fed three meals a day. Cats over 8 months old and adults know how to control their food intake. Once they feel full, they will stop eating. Therefore, adult cats can be fed a buffet. They also have the habit of eating small amounts of food frequently throughout the day.
3. Avoid developing unnecessary feeding habits.
Some cat owners try various methods to feed their cats when they don't eat. For example, if a cat occasionally refuses to eat or eats very little, some people will try to feed it by hand. The owner will be happy after the cat eats, and will continue to do so the second time. Over time, the cat will get used to thinking that only food fed by hand is edible. Little do they know that your small action will bring them endless trouble.
