My neighbor had a mother raccoon and three babies make a home in her chimney. She waited until they were old enough to climb out, then had a cover put on while they were away. My chimney has a cover that can be opened if using the fireplace. The chimney needs repaired, so it hasn't been used for many years.The neighbors squirrel went in from the chimney cap above the roof soffit. They have no near ground intake or exhaust. It crawled down the liner in the same chimney used for the water heater.
