After 4 failed offers, I’m finally under contract for a house. Overall it’s great but the seller has several cats, and I have family members with serious cat allergies. What would you recommend doing to get rid of all the dander? I’m already planning on having the carpets cleaned, but would love additional things I should be doing. My apartment lease goes beyond closing so I don’t have to move in right away.
