DANBURY — Two days after charging the owner of American Breeders pet shop with animal cruelty, police also arrested one of the managers of the Federal Road store. Kathy Seton, 29, of Cold Spring, N.Y., was charged Wednesday with animal cruelty. Her boss, Richard Doyle, 55, of Mahopac, N.Y., is facing three counts of the same charge for failing to properly care for two puppies and a kitten, authorities said. Doyle, who owns two other shops in New York, was arrested Monday after a four-month investigation by animal control officers from the state Department of Agriculture.
