I really enjoyed this one and hope you do too:
"NOVEL NOTES ... Jerome K. Jerome
She was the most motherly thing I have ever known. She was never happy without a family. Indeed, I cannot remember her when she hadn't a family in one stage or another. She was not very particular about what sort of family it was If she could not have kittens, then she would content herself with puppies or rats. Anything she could wash and feed seemed to satisfy her. I believe she would have brought up chickens if we had entrusted them to her.
All her brains must have run to motherliness, for she hadn't much sense. She could never tell the difference between her own children and other people's. She thought anything young was a kitten.
We once mixed up a spaniel puppy that had lost its own mother among her progeny. I shall never forget her astonishment when it first barked. She boxed both its ears, and then sat looking down at it with an expression of indignant sorrow that was really touching."
(Not so sure about the rats!!)
