Sentience is the ability to experience feelings and sensations. It may not necessarily imply higher cognitive functions such as awareness, reasoning, or complex thought processes. Sentience is an important concept in ethics, as the ability to experience happiness or suffering often forms a basis for determining which entities deserve moral consideration, particularly in utilitarianism.
Pleasure is experience that feels good, that involves the enjoyment of something. It contrasts with pain or suffering, which are forms of feeling bad. It is closely related to value, desire and action: humans and other conscious animals find pleasure enjoyable, positive or worthy of seeking. A great variety of activities may be experienced as pleasurable, like eating, having sex, listening to music or playing games. Pleasure is part of various other mental states such as ecstasy, euphoria and flow. Happiness and well-being are closely related to pleasure but not identical with it. There is no general agreement as to whether pleasure should be understood as a sensation, a quality of experiences, an attitude to experiences or otherwise. Pleasure plays a central role in the family of philosophical theories known as hedonism.
Animal welfare is the well-being of non-human animals. Formal standards of animal welfare vary between contexts, but are debated mostly by animal welfare groups, legislators, and academics. Animal welfare science uses measures such as longevity, disease, immunosuppression, behavior, physiology, and reproduction, although there is debate about which of these best indicate animal welfare.

Animal sexual behaviour takes many different forms, including within the same species. Common mating or reproductively motivated systems include monogamy, polygyny, polyandry, polygamy and promiscuity. Other sexual behaviour may be reproductively motivated or non-reproductively motivated.
Conversations regarding the ethics of eating meat are focused on whether or not it is moral to eat non-human animals. Ultimately, this is a debate that has been ongoing for millennia, and it remains one of the most prominent topics in food ethics. Individuals who promote meat consumption do so for a number of reasons, such as health, cultural traditions, religious beliefs, and scientific arguments that support the practice. Those who support meat consumption typically argue that making a meat-free diet mandatory would be wrong because it fails to consider the individual nutritional needs of humans at various stages of life, fails to account for biological differences between the sexes, ignores the reality of human evolution, ignores various cultural considerations, or because it would limit the adaptability of the human species.
Animal consciousness, or animal awareness, is the quality or state of self-awareness within an animal, or of being aware of an external object or something within itself. In humans, consciousness has been defined as: sentience, awareness, subjectivity, qualia, the ability to experience or to feel, wakefulness, having a sense of selfhood, and the executive control system of the mind. Despite the difficulty in definition, many philosophers believe there is a broadly shared underlying intuition about what consciousness is.

Animal non-reproductive sexual behavior encompasses sexual activities that non-human animals participate in which do not lead to the reproduction of the species. Although procreation continues to be the primary explanation for sexual behavior in animals, recent observations on animal behavior have given alternative reasons for the engagement in sexual activities by animals. Animals have been observed to engage in sex for social interaction bonding, exchange for significant materials, affection, mentorship pairings, sexual enjoyment, or as demonstration of social rank. Observed non-procreative sexual activities include non-copulatory mounting, oral sex, genital stimulation, anal stimulation, interspecies mating, same-sex sexual interaction, and acts of affection, although it is doubted that they have done this since the beginning of their existence. There have also been observations of sex with cub participants, as well as sex with dead animals.
Fish slaughter is the process of killing fish, typically after harvesting at sea or from fish farms. At least one trillion fish are killed each year for commercial consumption. Some fish harvesting uses controversial methods like suffocation in air, carbon-dioxide stunning, or ice chilling that have been called inhumane by many organizations such as the World Organisation for Animal Health. However, due to many culture's reliance on fish, some alternative methods of slaughter have been developed, including percussive stunning, pithing, shooting, and electrical stunning. While these methods are considered effective, they still face criticism, with some arguing that no method of fish slaughter can ever be truly humane.
Gary Edward Varner was an American philosopher specializing in environmental ethics, philosophical questions related to animal rights and animal welfare, and R. M. Hare's two-level utilitarianism. At the time of his death, he was an emeritus professor in the department of philosophy at Texas A&M University; he had been based at the university since 1990. He was educated at Arizona State University, the University of Georgia, and the University of Wisconsin–Madison; at Madison, where he was supervised by Jon Morline, he wrote one of the first doctoral theses on environmental ethics. Varner's first monograph was In Nature's Interests?, which was published by Oxford University Press in 1998. In the book, Varner defended a form of biocentric individualism, according to which all living entities have morally considerable interests.
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. This is an aspect of mating. Many aquatic animals use external fertilization, whereas internal fertilization may have developed from a need to maintain gametes in a liquid medium in the Late Ordovician epoch. Internal fertilization with many vertebrates occurs via cloacal copulation, known as cloacal kiss, while most mammals copulate vaginally, and many basal vertebrates reproduce sexually with external fertilization.

Animal Sentience: An Interdisciplinary Journal on Animal Feeling is a peer-reviewed academic journal. Its subject matter, animal sentience, concerns what and how nonhuman animals think and feel as well as the scientific and scholarly methods of investigating it and conveying the findings to the general public. The initial publisher was the Animal Studies Repository of the Institute for Science and Policy of The Humane Society of the United States, now the Animal Studies Repository of WellBeing International. The editor-in-chief is Stevan Harnad.
