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

<P0-S0> The domestic cat ("Felis silvestris catus" or "Felis catus") is a small, typically furry, carnivorous mammal. <P0-S1>  Cats are often valued by humans for companionship and for their ability to hunt vermin. <P0-S2>  There are more than 70 cat breeds, though different associations proclaim different numbers according to their standards. <P0-S3>  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. <SEP> <P1-S0> The biological family Felidae is a lineage of carnivorans that includes the cats. <P1-S1>  A member of this family is also called a felid. <P1-S2>  The characteristic features of cats have evolved to support a carnivorous lifestyle, with adaptations for ambush or stalking and short pursuit hunting. <P1-S3>  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. <P1-S4>  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. <SEP> <P2-S0> 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. <P2-S1>  It is the part of the body that corresponds roughly to the sacrum and coccyx in mammals, reptiles, and birds. <P2-S2>  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. <P2-S3>  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". <SEP> <P3-S0> 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. <P3-S1>  It had a long history in English law, although it was abolished by the [Animals Act 1971]. <P3-S2>  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. <P3-S3>  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. <P3-S4>  This tort is not available in New South Wales, The Australian Capital Territory, South Australia or New Zealand. <P3-S5>  In these jurisdictions the actions involving animals need to be in nuisance or negligence. <P3-S6>  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. <P3-S7>  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. <P3-S8>  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. <P3-S9>  It is common to distinguish between harmless animals and wild animals. <P3-S10>  No scienter is needed for wild animals. <P3-S11>  Animals are classed as wild or harmless on the basis of species or kind, not on the basis of being a tame individual. <P3-S12>  An elephant is considered wild irrespective of its use. <P3-S13>  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.
