There have been Catholics in every century, in nearly every country in the world. Christianity, as such, does not really need animals, if you are asking about civilizations, you need to ask a more specific question.
You don't need to be a Catholic.
Roman Catholic AnswerYes, you need to discuss this with your priest. If you marriage that you are in is valid, you should have no problems.
Animals do not need clothing
It needs to be near some trees and far away from other missions and catholic churches.
Yes. If the couple is converting to Catholicism, they will need a Catholic sponsor.
The answer to this is YES. You need to be baptized in the catholic church then only you are entitled to receive the sacrament of confirmation.
It is the Catholic faith that believes in purgatory and as that faith also believes that animals do not have souls, then no, logically, there can be no purgatory for animals.
If you asking if animals can be baptized and join the Church, then no. Animals do not have spirits made in the likeness of God that survive eternally.
They need Co2 from animals. Which is why we need them, for oxygen.
Catholic Charities, as with any other Catholic institution does not card people who are in need.
So they can escape from the animals that are pray on them. Animals need to move to get food and get away from danger. Animals need food for energy.
Why would catholics take care of animals any differently than any other Christian.
