my wife has raised pro. 100 baby tree rats in the last 25 yrs. no two act the same . some will eat things the others won't some feed in the morning some feed at noon some like people some are a$$ holes . we have had FL & Ohio born tree rats . most will stay in the nest box when it is raining out side even when they are in side . they will build & maintain a nest as soon as there eyes open. they are born to be squirrels
