A healthy way to feed baby Siamese kittens depends on their age as kittens under 6 weeks of age should be able to get all of their food needs from their mother's milk, according to the Animal Alliance of NYC. After 6 weeks, kittens can be weaned to dry food.
Kittens that are undergoing the weaning process need dry or canned kitten food that they can eat as they begin to eat solid food. The process of weaning takes between 8 and 10 weeks, notes the American Society for the Prevention of Cruelty to Animals. If the Siamese kittens were taken from their mother before they had a chance to be weaned, they may need to be bottle fed, reports the Animal Alliance of NYC.
