Question: A cat is part of a biological family that, given their need for animal nutrients, are sometimes referred to as what?

Context paragraphs:
Anatidae: The Anatidae are the biological family of birds that includes ducks, geese, and swans.  The family has a cosmopolitan distribution, occurring on all the world's continents.  These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water.  The family contains around 146 species in 43 genera.  (The magpie goose is no longer considered to be part of the Anatidae, but is placed in its own family Anseranatidae.)

Cat: The domestic cat ("Felis silvestris catus" or "Felis catus") is a small, typically furry, carnivorous mammal.  They are often called house cats when kept as indoor pets or simply cats when there is no need to distinguish them from other felids and felines.  Cats are often valued by humans for companionship and for their ability to hunt vermin.  There are more than 70 cat breeds, though different associations proclaim different numbers according to their standards.

Felidae: The biological family Felidae is a lineage of carnivorans that includes the cats.  A member of this family is also called a felid.  The characteristic features of cats have evolved to support a carnivorous lifestyle, with adaptations for ambush or stalking and short pursuit hunting.  They have gracile and muscular bodies, strong flexible forelimbs and retractable claws for holding prey, dental and cranial adaptations for a strong bite, and often have characteristic striped or spotted coat patterns for camouflage.  Cats are obligate carnivores, meaning they are dependent on nutrients in animal flesh for survival, and because of the large proportion of meat in their diet are sometimes referred to as hypercarnivores. Of the 13 terrestrial families in the order Carnivora, they are the strictest carnivores.

Poly(amidoamine): Poly(amidoamine), or PAMAM, is a class of dendrimer which is made of repetitively branched subunits of amide and amine functionality.  PAMAM dendrimers, sometimes referred to by the trade name Starburst, have been extensively studied since their synthesis in 1985, and represent the most well-characterized dendrimer family as well as the first to be commercialized.  Like other dendrimers, PAMAMs have a sphere-like shape overall, and are typified by an internal molecular architecture consisting of tree-like branching, with each outward 'layer', or generation, containing exponentially more branching points.  This branched architecture distinguishes PAMAMs and other dendrimers from traditional polymers, as it allows for low polydispersity and a high level of structural control during synthesis, and gives rise to a large number of surface sites relative to the total molecular volume.  Moreover, PAMAM dendrimers exhibit greater biocompatibility than other dendrimer families, perhaps due to the combination of surface amines and interior amide bonds; these bonding motifs are highly reminiscent of innate biological chemistry and endow PAMAM dendrimers with properties similar to that of globular proteins.  The relative ease/low cost of synthesis of PAMAM dendrimers (especially relative to similarly-sized biological molecules such as proteins and antibodies), along with their biocompatibility, structural control, and functionalizability, have made PAMAMs viable candidates for application in drug development, biochemistry, and nanotechnology.

Scienter: The scienter action is a category within [tort] law in some[common law] jurisdictions which deals with the damage done by an animal directly to a human.  It had a long history in English law, although it was abolished by the [Animals Act 1971].  An action in those common law jurisdictions where it has not been extinguished by statute, is in addition to the torts of negligence and nuisance, or more bespoke torts like cattle trespass.  Where an animal is known to behave in a certain way, and that is expressed on a person causing injury, an action can be taken in this tort.  This tort is not available in New South Wales, The Australian Capital Territory, South Australia or New Zealand.  In these jurisdictions the actions involving animals need to be in nuisance or negligence.  To be successful the plaintiff needs to take action against the person in control of the animal, and it is strict liability, requiring no more than proof of injury, that the animal had a problematic trait, and the person in control knew about the trait in the animal.  Being strict liability, there is no need to argue fault in the form of wilful intent or negligence on the part of the animal or its controller.  The only defence is if it can be proved the plaintiff voluntarily assumed the risk of injury by their actions, or if the plaintiff was the cause of the injury.  It is common to distinguish between harmless animals and wild animals.  No scienter is needed for wild animals.  Animals are classed as wild or harmless on the basis of species or kind, not on the basis of being a tame individual.  An elephant is considered wild irrespective of its use.  The scienter action is referred to in Rylands v. Fletcher in that one who keeps a wild thing “must keep it at his peril” to make reference to part of Justice Colin Blackburn’s comment.

Animal Genetic Resources for Food and Agriculture: Animal genetic resources for food and agriculture are a subset of genetic resources (defined by the Convention on Biological Diversity as "genetic material of actual or potential value") and a specific element of agricultural biodiversity.  The term animal genetic resources is often used to refer specifically to the genetic resources of avian and mammalian species used in or potentially used for food and agriculture purposes.  The term "animal genetic resources for food and agriculture" is often shortened to "farm animal genetic resources" or simply "animal genetic resources" and sometimes referred to as "livestock biodiversity" or simply "livestock diversity".

Tail: The tail is the section at the rear end of an animal's body; in general, the term refers to a distinct, flexible appendage to the torso.  It is the part of the body that corresponds roughly to the sacrum and coccyx in mammals, reptiles, and birds.  While tails are primarily a feature of vertebrates, some invertebrates including scorpions and springtails, as well as snails and slugs, have tail-like appendages that are sometimes referred to as tails.  Tailed objects are sometimes referred to as "caudate" and the part of the body associated with or proximal to the tail are given the adjective "caudal".

Upland goose: The upland goose or Magellan Goose ("Chloephaga picta") is a sheldgoose of the shelduck-sheldgoose subfamily of the Anatidae, the biological family that includes the ducks and most duck-like waterfowl such as the geese and swans.  This bird is indigenous to the southern part of South America.

Marmoset: The marmosets also known as zaris ( ) are 22 New World monkey species of the genera "Callithrix", "Cebuella", "Callibella", and "Mico".  All four genera are part of the biological family Callitrichidae.  The term "marmoset" is also used in reference to the Goeldi's marmoset, "Callimico goeldii", which is closely related.

Culture and social cognition: Culture & Social Cognition is the relationship between human culture and human cognitive capabilities.  Cultural cognitive evolution proposes that humans’ unique cognitive capacities are not solely due to biological inheritance, but are in fact due in large part to cultural transmission and evolution (Tomasello, 1999).  Modern humans and great apes are separated evolutionarily by about six million years.  Proponents of cultural evolution argue that this would not have been enough time for humans to develop the advanced cognitive capabilities required to create tools, language, and build societies through biological evolution.  Biological evolution could not have individually produced each of these cognitive capabilities within that period of time.  Instead, humans must have evolved the capacity to learn through cultural transmission (Tomasello, 1999).  This provides a more plausible explanation that would fit within the given time frame.  Instead of having to biologically account for each cognitive mechanism that distinguishes modern humans from previous relatives, one would only have to account for one significant biological adaptation for cultural learning.  According to this view, the ability to learn through cultural transmission is what distinguishes humans from other primates (Tomasello, 1999).  Cultural learning allows humans to build on existing knowledge and make collective advancements, also known as the “ratchet effect”.  The ratchet effect simply refers to the way in which humans continuously add on to existing knowledge through modifications and improvements.  This unique ability distinguishes humans from related primates, who do not seem to build collaborative knowledge over time.  Instead, primates seem to build individual knowledge, in which the expertise of one animal is not built on by others, and does not progress across time.
