My husband is severely asthmatic and despite his not visiting any more and my extensive efforts to "decontaminate" myself and my clothing when I get home from my visit he wheezes. Son and daughter-in-law say the cats are part of their family and won't give them up. Now I do not know what to do since I do not want to give up my son or his children but cannot go on causing my husband to have a life-threatening illness. Perhaps my efforts to decontaminate are not good enough. Is there anyone who has figured out how to do it and have it work? We cannot find a solution thus far.
