What innate behavior is the Siamese cats are born with?

Siamese cats are born with the innate behavior of suckling. As soon as they are born, they instinctively crawl towards their mother and start suckling on her milk. This behavior is essential for their survival, as it allows them to receive the necessary nutrients from their mother's milk in order to grow and develop. This instinct is programmed into their neural systems from birth, and they do not need to be taught this behavior in order to perform it.
