You’re welcome. It’s a learning curve - and they teach us! It takes some willpower not to keep tinkering with their cages which for us may be creative but for them is a complete invasion of privacy!
He may still get stressed by changes in the cage - they tend to accept something new being added but don’t like things being moved or removed. So if you can pop a bit of substrate in and mix it in a bit at the same time as popping the new house in it’ll be only one disturbance
