I was watching an episode today where Rose was addicted to the pain
medication... She made an excuse about how it was the anniversary of
the death of her beloved cat "Fluffy"... Dorothy replied that Rose
never had cats, she was allergic...

From an earlier episode when they remember how they all met, Rose had
a cat that she loved "Mr. Peepers" and she had to move because the
landlord wouldn't let her keep it...

Two very different stories... I guess most people wouldn't see an
entire series in two weeks and might not realize this happened?
