Here is what the Catechism of the Catholic Church says...
Animals are God's creatures. He surrounds them with his providential care. By their mere existence they bless him and give him glory. Thus we humans owe them kindness. We should recall the gentleness with which saints like St. Francis of Assisi or St. Philip Neri treated animals.
God entrusted animals to the stewardship of those whom he created in his own image meaning us humans. Hence it is legitimate to use animals for food and clothing. They may be domesticated to help human in their work and leisure.
It is contrary to human dignity to cause animals to suffer or die needlessly. It is likewise unworthy to spend money on them that should as a priority go to the relief of human misery. One can love animals; one should not direct to them the affection due only to persons.
