Nah, when animals go from feeding themselves to being fed by humans and from living in wild habitats to human environments, their bodies do not need the adaptations they had, and instead are pressured towards new ones that are similar to our pets because they experience similar evolutionary pressures as our pets.

Raccoons are simply going thorough the same changes that our pets already went through when they were domesticated. It's not that raccoons are looking more like our pets, it's that both raccoons and our pets are looking less like themselves and more like "domesticated", and our pets are further ahead on this transition.
