Yes, wet food is good for cats. While dry food adds volume and provides calories, wet food is easily digestible and a better option for cats with digestion issues or other infections. You should give your cat wet food at least once daily to keep its digestive system in order.
How much wet food you feed your cat should depend on its weight and the number of calories you want to provide it per day. Usually, for a cat that weighs up to 5lbs, it is recommended to give them 4-5 ounces of food every day, divided over two meals.
Your cat's bowl should not have food that has been out for over four hours. Even if your cat prefers to take a few sittings to finish the food, you should replace it with fresh food after washing the bowl properly. You do not want any bacteria to infect your cat.
Wet food, as well as dry food, have their own unique benefits. Dry food contains a more significant amount of carbohydrates, and wet food is a good source of protein. The heating process in the packaging of wet food makes it pathogen-free. The main difference lies in their moisture levels.
