It had a cartoon of a rather portly grey and white tabby cat slaving away, pen to paper, and read:
Happy Mother's Day from the Cat.
I am writing you this Mother's Day Card, which is a difficult thing because I am a cat, because I love you very much and because, recently, a terribly rumor has come to light and I need your reassurance that it isn't so...
and inside it said:
Tell me I wasn't adopted?
Mao Tse Cat
