Many churches will have "the blessing of the pets" or "the blessing of the animals" in honor of the Feast of St. Francis in October. I was once lucky enough to attend one of the most well-known of these ceremonies at the Cathedral of St. John the Divine in Manhattan.
When I first heard of this as a kid, I was offended because I thought we needed to be blessed by the animals, not the other way around! In any case, it's usually a very moving (and humorous) ceremony.
"Creatures minister to our needs every day. Without them, we could not live, and through them the human race greatly offends the Creator every time we fail to appreciate so great a blessing."
