What if a cat and raccoon breed?
It is genetically impossible for a raccoon and a domestic cat to mate. They are too far removed from each other on the mammal tree.
This will never happen. Animals simply happen to be much smarter than many people and they certainly are a lot nicer mating with their own kind.
"It is genetically impossible for domestic cats to breed with either raccoons or bobcats, as we in the cat fancy know, because they are of different genera and do not hybridize." according to the Cat Fanciers Association in their article about a breed of cat known as Maine Coon Cat, cited here: http://www.cfainc.org/breeds/profiles/articles/maine.html
