Arlington — Brooklyn was first to arrive with Luther in tow. The Rev. Ann Barker descended the stairs at St. John’s Episcopal Church offering greetings. Elaina Link arrived next with Twinkle, her young tabby cat for the blessing of the pets. The blessing of the pets is held annually on a weekend near Oct. 4, the feast day of St. Francis of Assisi. St. John’s Episcopal Church is located on S. Lexington Street in South Arlington.
