"Was it something I said?"

I hope that you really believe me that it was not something you said/did, because it wasn't. It really was the presence of a cat - I'm highly allergic, and if I had stayed, it would have progressed to me puking up bile and being unable to move from your bathroom floor, gripping the toilet in sheer agony and begging you to shoot me. I guess, just in case I run into you again, that I'm just going to have to take allergy pills before I go to the bar. For what it's worth, I would have liked to stay, but at that point, I really had to leave or face getting so sick that I'd have to go to the ER.

But it was fun, and worth the risk of an allergy attack.
