How do you cope with your allergies to cats if you have one? Besides getting rid of the cat?

May Have To Give Up. You can try medication (antihistamines and/or steroid nose sprays), neti pot, wash the cat regularly to remove dander, clean and vacuum the house frequently to reduce the dander in the house, limit the range where the cat can roam in the house, ban the cat from areas you spend the most time (bedroom), etc.
