It is unlikely that your son's typical allergic reaction was caused by contact with the mohair blanket. Much more likely is that he is allergic to cats.He seems to be slightly less allergic to your cat , but still sufficiently allergic to have constant nasal symptoms. Your son should be tested to see what he is allergic to including a test for cats.You should have an antihistamine syrup such as Allecet at home in case your son has another more severe reaction to cat contact in the future. The dose of Allecet is 5ml given in a single dose only once aday.
