How to get rid of cat dander?

My husband and I are in the process of buying a house. The current owners have a cat and I am highly allergic. What steps do you suggest we take to get rid of the dander? Will having the carpets cleaned be enough?

It will really depend on how severe your allergies are. Some people just can't live in a house that has had a pet live there, especially cats. Some people need to repaint walls, clean baseboards, remove carpet and replace with wood. Other people will be fine with a carpet cleaning. 

I would recommend having the carpets and all fabrics cleaned such as drapes. If there's blinds thoroughly clean each blind. That could be plenty. THere are special clenaers meant to remove dander buy them. You may have to go over the house several times, again depending on the severity of your allergies.
