Constant cleaning. Even if you choose to rehome your pet, you will have allergy symptoms for several weeks due to significant levels of lingering pet allergens. Have someone else do a thorough cleaning that includes washing the ceilings and walls. All bedding including sheets, pillows, bedspreads, and blankets will need replacing since it’s difficult to completely launder away pet allergens. Either replace your mattress and box springs or cover them in allergen-blocking covers. If you decide to keep your pet, a fenced-in area can keep them safe, and heated or air-conditioned sheds can keep them comfortable if you need a break. Establish “pet free zones” in your home including your bedroom. Enlist a family member or friend to bathe your pet weekly.
