Cats cannot eat food:

1. Milk and dairy products. Most cats are lactose intolerant, and their digestive systems cannot process dairy products. Therefore, if the cat is fed milk or dairy products, the cat will be unable to digest it and cause diarrhea.

2. Alcohol and all alcoholic beverages. Beer, spirits, wine, and food containing alcohol are not good for cats. Just like humans, alcohol affects cats' livers and brains, and just a little bit is enough to be lethal. Two teaspoons of whiskey will knock a five-pound cat unconscious, and one more teaspoon will kill it.

3. A large amount of animal liver. There is nothing wrong with feeding your cat a small amount of liver, but eating too much liver may cause vitamin A poisoning. This can seriously affect your cat's bones. Symptoms include bone deformities, bone growth in the elbows and spine, and osteoporosis. Vitamin A poisoning can also cause death.

What foods are good for cats to eat:

1. Chicken breast. Chicken breast contains very low fat and is rich in protein. Eating it is not likely to cause obesity or high cholesterol. You can cook chicken breasts in plain water for your cat to eat. 2-3 times a week is enough, otherwise it will cause the cat to be picky about food.

2. Fish. We all know that cats like to eat fish, and fish is also very suitable for cats to eat because fish is rich in protein, easy to digest, and rich in minerals. But don’t feed it too often, as this will make the cat tired of eating.

3. Pumpkin. Pumpkin contains folic acid, calcium, phosphorus and other trace elements, which can help cats clean their intestines and expel hair balls.
