Are animals allowed to attend the ceremony (family pets, decorative doves, etc)?
Generally the church isn’t the place for animals, although they do show up sometimes at Christmas Masses and in October for the Blessing of the Animals. One Palm Sunday I saw a bishop ride into the church on a burro. So maybe if the pets were in little pet cages or bags or something it would be all right. Flying things like doves must be in cages — lined with newspaper, please. If one of those things gets loose you have a devil of a time getting it out of the church. In any event, talk to your pastor.
