Catwings - Ursula K. Le Guin, S.D. Schindler
A cat gives birth to four kittens, but they are different - they have wings! After they have grown some and can fly, they leave the city in search of some place safe for them to live.This is such a cute and sweet book. It's not very long at all, but a very nice story. I really like the four cats with wings and I'm going to read the other books in the series as soon as I can.
