A pair of skunks have had a brood three years running under a friends porch. His cat gets along well with them. The friend in in a semi-rural area outside city limits, so the skunks have never been provoked into retaliation, at least near the house.
A son in the Vancouver area has occasional raccoon problems, but keeping the garbage bins tightly closed seems to have directed them elsewhere.

In our city, cats are not permitted to roam loose, so no cat doors. Some problems with eastern grey squirrels, which were deliberately brought in years ago by a moronic displaced Torontonian, and exist nowhere else in the prairie provinces. Raccoons haven't migrated into our province yet.
