Being sentient means to have the capacity to have positive and negative experiences, such as feeling pain and pleasure. This applies at the very least to all animals with centralised nervous systems. Sentient beings have their very own unique personalities. We should refer to them as “he/she”, “them/they” or by species. The words “it” or “thing” should not be used to refer to an animal, and “who” is used rather than “that”. If you do not know the gender, then choose one: “he” or “she”. Even if your gender choice is wrong, it is more respectful than “it”. This is an important way of demonstrating the respect we ask others to afford all animals.
