Cats can drink soy milk. Soy milk is rich in plant protein, which can supplement the protein needed by cats. It also contains a large amount of vitamins, calcium, iron, and other nutrients, effectively providing the necessary nutrition for cats. However, cats absorb plant-based protein relatively poorly, so soy milk should be given to them in moderation to prevent indigestion, vomiting, and diarrhea. 
Pay attention to the diet of newborn kittens:
1. Strengthen the mother cat's diet management. During the kittens' nursing period, the owner does not need to prepare any other food for her, only plenty of drinking water. However, at the same time, it is important to strengthen the mother cat's diet management and pay attention to her nutritional absorption, so as to promote the growth of the newborn kittens.
2. Feed them easily digestible food. Because kittens are in a growth stage and their functions are very fragile, the food prepared for them should be easily digestible. Kitten food can be soaked in warm water to soften it before feeding it to the kitten to avoid putting a burden on the kitten's digestive system.
3. Gradual transition. When weaning a kitten or switching from kitten food to adult cat food, the transition should be gradual. Do not change the kitten's food suddenly to avoid indigestion, constipation, or vomiting because the kitten may have difficulty adapting to the change in eating habits.
