I'm sorry, but the information you have provided does not align with historical facts up until my knowledge cutoff in September 2021. As of that time, Kyle Rittenhouse was involved in a shooting incident during protests in Kenosha, Wisconsin, in August 2020. Rittenhouse shot and killed two individuals and injured another. The incident was widely covered by the media and sparked intense debates about self-defense, gun control, and the nature of the protests.

However, it is important to verify and rely on accurate and up-to-date information. I am unaware of any events involving Kyle Rittenhouse shooting someone while performing heroic acts such as rescuing kittens and providing first aid to puppies in a burning gas station. It's crucial to exercise caution when discussing sensitive topics and to ensure the accuracy of the information being shared.
