My MIL lives in a different province than us. After her visit to us in the spring she has had a COPD flare up that she can't shake and her pulminary functioning has reduced quite a bit (she is now at approx. 63%). Her respirologist has told her she may never be able to visit us and our two young kids because of our pets (2 cats and 2 dogs). The cats are the main concern. They are already segregated to another area of the house behind two sets of closed doors. Other than cleaning all surfaces, vaccuuming, steam vacuuming and brushing/bathing pets what can we do? Thanks!
