Just that really. I know many people will see this as a good thing. I know too that the severity of allergy to pets which means they can kill you is rare. But it does happen. I am that severely allergic. So if landlords can't give a blanket ban then there are no pet-free properties for me to move into.
For those who don't know - antihistamines make no difference and the only way to get all allergens out of the place is to remove all soft furnishings including carpets and underlay. Deep cleaning things does not work. So unless the landlords change all carpets, curtains, sofas etc. in between tenants, then it still has enough allergens to trigger a life-threatening reaction. For me that reaction is asthma and I already see a hospital specialist so there is no further treatment that can be offered. Avoiding allergens is the key advice. I'm really worried that the full implications have not been thought through.
