If she did she never told me.
She was a lovely character but always reminded me of a cross between Winnie the Pooh (the bear of little brain) and the Dish of the Day (H2G2).
The two of them together were fascinating - both from the same litter so exactly the same genetics but Titch (who was the runt of the litter) was into absolutely everything and had a real intelligence, Crackers was almost the opposite - fascinated by her sister she could watch for hours.
She was called Crackers because as a kitten she used to love top chase butterflies in the garden (that year we had a plague of cabbage whites so she caught lots). She leaped around the garden like a mad thing with a spring in the tail. In the last 10 years she has steady become more and more stately!
