Hi NikitaSue,
Firstly where is the mold exactly and is it visible inside your home ? Is there additional moisture damage that may require structural repairs ? If so then you might need to move out for a few days to the home of family or friends and take the buns with you, especially if the mold has to be cleaned aggresively with chemicals. However, if it is contained and has not caused major damage you may be able to get your landlord to supply the chemicals and you or a friend carry out the work. It is also entirely possible he might arrange contractors who would not have any reason to report the presence of your rabbits...
