I found a kitten on a walk what do I do?

You sound like a very loving person, and don't worry about your spelling - your English is good! Anyway, you are doing the right thing. I'm not too sure about the dog food, but the kitten will probably be fine. It sounds like he lost his mama or someone abandoned him - how sad for the poor baby! He will turn out to love you so much, and you will be his mama for life! Good luck! Amusez-vous avec votre chaton!
