Consider yourself lucky ... she doesn't come over, and you don't have to deal with her. I wish some members of my family wouldn't come over because of my dogs!

However, I have to admit, I do not ever go to my SIL's house, because of her cats. (I would not, however, say as much as rudely as your aunt did.) It's not that I don't like her cats, they are nice cats. But she has a lot of them, and she isn't the best housekeeper, and consequently there is cat hair all over the furniture. I am very allergic to cats, and a visit to her house is not at all a good thing for me.
