In the Latin Church, 4 October is the Feast Day of St. Francis of Assisi, patron saint of animals and ecology. Some parishes bless the animals
on or near this day:
At Franciscan churches, a friar with brown robe and white cord often welcomes each animal with a special prayer. As the prayer is offered, the pet is gently sprinkled with holy water. Believe it or not, most pets receive this sacramental spritz with dignity, though I must admit I have seen some cats flatten their ears a bit.
Do Orthodox have a saint who might be considered a patron saint of ecology, and do the Orthodox have any doctrinal or traditional hesitation to blessing animals?
