I guess Sadie fet that her job was done, that her Kittens were in a good pace, and that it was her turn to become an Angel.
She certainy is one Amazing Cat, and a Cat who show up we humans in terms of being intelligent and resouceful.
Sadie will have her wings of Silver and Gold, and that will be quite a reunion
when Sadie and You and Her Mnay Kittens are together agin in love.
One Fine Day
