Books like Catwings Return

Identical in format and length to its predecessor, Catwings , this new book picks up where that one left off. The four winged cats Thelma, Roger, Harriet and James are content in the country barn where they live, secretly cared for by humans Hank and Susan. But they would like to see their mother, and the dumpster where they were born. Only James and Harriet make the trip, and learn that the slums are being destroyed by demolition crews!
