Don't panic about the idea of a young raccoon being around your cats, unless you live in an area with higher risk of rabies. (I live in a state with low totals, and to my knowledge no cases in raccoons.) Like any other wild animal, they can carry other diseases, as well, and you may want to check about how high the risk might be in your own area. But I have been feeding the raccoons here for ten years. That's how I got two of the three cats I have "owned;" as strays looking for a food source, they came to take the food I had put out for the raccoons. As a whole, the raccoons and cats have tolerated each other. Many a time I found one of my indoor-outdoor cats and a raccoon both waiting on the porch for me. Many a time I've seen a raccoon back off when he got too close and Guard Cat or Purdy would take a swat at him. (Red Cat chooses flight instead.) But it would only take once for a raccoon to decide to become aggressive instead and the cat would come out the loser. From what I've seen, I would expect that would most likely happen with a larger male or with a mama raccoon who was protecting her young or if food was in short supply.
So while I want to ease your mind about any immediate risk while the raccoon is still a baby (unless you are in a high rabies area), I agree that if you are feeding a feral colony, your best bet would be to find a wildlife rehabilitator. If you don't find one near you on the list in the link provided above, call the Fish and Wildlife Department or whatever it is called in your state and see if there are any in your area. I see that the one nearest me does not appear to be listed.
