He is allergic to cats, so when he's rolling up carpet and cleaning out air-filters, I'd hate to find out he had some sort of wild allergy attack because this tenant weaseled his way out of the paragraph prohibiting pets.

I'd hate for someone to move in and have an allergy to pets, and they were unaware that pets would be in the house.
