Newborn kittens should not drink soy milk powder. The main ingredients of soy milk powder are soybeans and milk. Soybeans contain a large amount of starch, and milk contains large molecules of lactose. Soybeans can cause gastrointestinal upset in kittens, and the large molecules of lactose in milk are not suitable for their digestive systems, easily inducing diarrhea. Furthermore, soy milk powder contains saccharin, preservatives, and other additives, which can damage a kitten's kidneys. Newborn kittens are best fed their mother's milk, as it contains many antibodies and strengthens their immunity. If artificially fed, probiotics can be added to goat milk powder regularly to aid digestion. 
How to feed newborn kittens:
1. Food: Primarily goat milk powder, fed 5-6 times a day. Establish a feeding schedule based on the cat's and owner's availability, or feed the kitten whenever it's hungry. If goat milk powder is unavailable, rice water or thin millet porridge can be used as a substitute, but cow's milk should be avoided. Kittens should eat small, frequent meals, 5-6 times a day, or adjust feeding times according to the owner's schedule.
2. Feeding amount: Start by feeding 4ml of goat milk. If the kitten smacks its lips after drinking, gradually increase the amount. After one day of testing, the feeding amount can be fixed according to the kitten's size.
3. Feeding Supplies: Kittens can be fed using a 10ml syringe (without the needle) or a small baby bottle. When purchasing kitten goat milk powder, you can first inquire whether it comes with matching feeding supplies, such as a small syringe or a small baby bottle, what temperature it can withstand, and how to use it. After preparing the goat milk, let it stand to cool down. Once the temperature reaches the temperature of the back of your hand, you can feed it to the kitten.
