Karen-
let me start by saying I am sorry for your losses. It is hard to tell what may have been going on, but with the nasal discharge it sounds like Upper Respiratory Infection may have played at least a part in their passings. Perhaps contacting a small anima vet for advice would be the next best step at this point. They can give you a clearer picture of what may have happened, and can help you to clean properly before bringing another animal into your home. Again, sorry about your losses.
