Try to get ahold of a product called Fresh Cab.It was developed by a farm wife especially for this purpose.It is made from ground corn cobs in a tea-bag type bag that has a potpourri type smell.Very nice to us.However,with a mouse's keen sense of smell,it doesn't care for it.I will try to get the web address,but you may be able to do a search and come up with it on your own.I'm just saying that there is a product made just for this situation.
