You have no idea how excited I am to read this. I have been taking care of a feral cat colony for a couple months. I have 2 kittens that I have domesticated and can play with.
I also have a racoon named Wagner that lives in the drainage colvert thing in my backyard and steals my cat food.
I've been trying to find a solution to the same problem. I was told by animal control that they can relocate Wagner but another raccoon will just move into his home. Wagner may steal my cats' food and be a big pest but he's not really mean. If your raccoons are trying to attack your kittens, you might want to have them relocated.
