In case I don’t find a home for the school iggy, what would the possibility of housing him in the basement when it get colder. This is not a heated/finished basement, but the room that has the furnace stays around the mid 60’s in the winter (of course he would have lighting & heat). You are comfortable going downstairs in a t-shirt. During the fall and winter it stays quite dry. When I raised rabbits and guinea pig I housed them in the basement year round.
