By the way, no Catholic has ever prayed for a dead person. Our God is the God of the living, not the dead (Matthew 12:26-27)

Prayers for the Dead
This subject will be treated under the following three heads:
I. General Statement and Proof of Catholic Doctrine;
II. Questions of Detail;
III. Practice in the British and Irish Churches.
I. GENERAL STATEMENT AND PROOF
Catholic teaching regarding prayers for the dead is bound up inseparably with the doctrine of purgatory and the more general doctrine of the communion of the saints, which is an article of the Apostle’s Creed. The definition of the Council of Trent (Sess. XXV), “that purgatory exists, and that the souls detained therein are helped by the suffrages of the faithful, but especially by the acceptable sacrifice of the altar”, is merely a restatement in brief of the traditional teaching which had already been embodied in more than one authoritative formula – as in the creed prescribed for converted Waldenses by Innocent III in 1210 (Denzinger, Enchiridion, n. 3 73) and more fully in the profession of faith accepted for the Greeks by Michael Palaeologus at the Second Ecumenical Council of Florence in 1439: “[We define] likewise, that if the truly penitent die in the love of God, before they have made satisfaction by worthy fruits of penance for their sins of commission and omission, their souls are purified by purgatorial pains after death; and that for relief from these pains they are benefitted by the suffrages of the faithful in this life, that is, by Masses, prayers, and almsgiving, and by the other offices of piety usually performed by the faithful for one another according to the practice [instituta] of the Church” (ibid., n. 588). Hence, under “suffrages” for the dead, which are defined to be legitimate and efficacious, are included not only formal supplications, but every kind of pious work that may be offered for the spiritual benefit of others, and it is in this comprehensive sense that we speak of prayers in the present article. As is clear from this general statement, the Church does not recognize the limitation upon which even modern Protestants often insist, that prayers for the dead, while legitimate and commendable as a private practice, are to be excluded from her public offices. The most efficacious of all prayers, in Catholic teaching, is the essentially public office, the Sacrifice of the Mass.
