@Catherine53 that seems the be the same list of alleriges I suffered as an asthmatic child, then I suddenly "grew out" of them as soon as I reached my teens, apart from cat hair. Oh, and Asprin 😕
@Sarah977 That is interesting (re the saliva) but oddly black cat hair doesn't bother me apart from giving me an itchy face. A tabby or ginger really set me off. I have become more tolerant to it as the years rolled on, takes up to a day in a place with a cat now, whereas it would come on in minutes when I were younger.
The feathers allergy returned when I was in my 50s, along with a surprise discovery that a night in a room with a plug in air freshner left me very short of breath the next day, so I steer clear of those things.
I have a lot of sympathy with people who get severe reactions, I'm grateful that for me they are just minor discomforts, not life threatening.
Actually when we fitted out our guest room we made sure all the bedding and matresses were hypoallergenic and hope by now its more than clear enough in our listing that we have pets. Or maybe some enterprising hosts might make a selling point of adding Pet Free to their listings title, room permitting?
