souls of animals:

In view of the historic lack of charity, tolerance, and justice regarding humans' treatment of other creatures, it is critical to humanity's own salvation, collective and personal, to appreciate in all creatures their actual or potential role as cousins to us and to Christ, and the fact that they are simply less [or more: Orcas, etc.] intellectually developed, but with God-given souls -- of one capacity & nature or another -- who are also capable of growth in grace & ultimate salvation.

We as humans with better access to Christ's teachings have a major responsibility to bring -- where possible -- that teaching to these other of our relatives, as well as formal baptism instead of just baptism of desire, when the situation 'of significant appreciation by them of that teaching' seems to call for it.
