Two loving and personable outdoor cats need a new home (Chester Township, Clinton County)

My son and his family have two loving and personable outdoor cats: - a 6yo neutered male, white and tan, named Oliver - a 4yo spayed female, orange, named Ava They are moving and cannot take them to their new home, so I am caring for them for the moment.
They are used to being outside, but do need someplace safe to shelter in during inclement weather.
Ideal situation would be someone in the country with a barn or other outbuilding where they can chase mice and moles.
