If newborn kittens don't have goat milk powder, you can take the following measures:
1. If conditions permit, kittens should be fed their mother's milk first, as this is the most suitable source of nutrition for kittens and can enhance their immunity.
2. If breast milk or goat milk powder is unavailable, consider using pet-specific low-lactose cow's milk or infant rice cereal as a temporary alternative.

3. Use a syringe or pet bottle to feed the kitten slowly to avoid it swallowing too much air and causing bloating.
4. As the kitten gets a little older, you can gradually add softened cat food or nutritional paste to provide more comprehensive nutrition.
