Rats are various medium-sized, long-tailed rodents. Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus Rattus. Other rat genera include Neotoma, Bandicota and Dipodomys.
An animal shelter or pound is a place where stray, lost, abandoned or surrendered animals – mostly dogs and cats – are housed. The word "pound" has its origins in the animal pounds of agricultural communities, where stray livestock would be penned or impounded until they were claimed by their owners.
Trap–neuter–return (TNR), also known as trap–neuter–release, is a controversial method that attempts to manage populations of feral cats. The process involves live-trapping the cats, having them neutered, ear-tipped for identification, and, if possible, vaccinated, then releasing them back into the outdoors. If the location is deemed unsafe or otherwise inappropriate, the cats may be relocated to other appropriate areas. Ideally, friendly adults and kittens young enough to be easily socialized are retained and placed for adoption. Feral cats cannot be socialized, shun most human interaction and do not fare well in confinement, so they are not retained. Cats suffering from severe medical problems such as terminal, contagious, or untreatable illnesses or injuries are often euthanized.
A black cat is a domestic cat with black fur that may be a specific breed, or a common domestic cat of no particular or mixed breed. All-black fur pigmentation is slightly more prevalent in male cats than female cats. Most black cats have golden irises due to their high melanin pigment content. Black cats are the subject of myth, legend, and superstition. They are often associated with witches and bad luck in European folklore.
A feral cat or a stray cat is an unowned domestic cat that lives outdoors and avoids human contact; it does not allow itself to be handled or touched, and usually remains hidden from humans. Feral cats may breed over dozens of generations and become an aggressive local apex predator in urban, savannah and bushland environments. Some feral cats may become more comfortable with people who regularly feed them, but even with long-term attempts at socialization, they usually remain aloof and are most active after dusk. Of the 700 million cats in the world, an estimated 480 million are feral.
The ecological restoration of islands, or island restoration, is the application of the principles of ecological restoration to islands and island groups. Islands, due to their isolation, are home to many of the world's endemic species, as well as important breeding grounds for seabirds and some marine mammals. Their ecosystems are also very vulnerable to human disturbance and particularly to introduced species, due to their small size. Island groups, such as New Zealand and Hawaii, have undergone substantial extinctions and losses of habitat. Since the 1950s several organisations and government agencies around the world have worked to restore islands to their original states; New Zealand has used them to hold natural populations of species that would otherwise be unable to survive in the wild. The principal components of island restoration are the removal of introduced species and the reintroduction of native species.
The farm cat, also known as a barn cat, is a domestic cat, usually of mixed breed, that lives primarily outdoors, in a feral or semi-feral condition on agricultural properties, usually sheltering in outbuildings. They eat assorted vermin such as rodents and other small animals that live in or around outbuildings and farm fields. The need for the farm cat may have been the original reason cats were domesticated, to keep rodents from consuming or contaminating grain crops stored for later human consumption. They are still commonly kept for their effectiveness at controlling undesired vermin found on farms, ranches, greenhouses, and even drug farms, which would otherwise eat or contaminate crops, especially grain or feed stocks. Farm cats hunt the rodent population, and their pheromones keep further rodents from filling the void.
A no-kill shelter is an animal shelter that does not kill healthy or treatable animals based on time limits or capacity, reserving euthanasia for terminally ill animals, animals suffering poor quality of life, or those considered dangerous to public safety. A no-kill shelter uses many strategies to promote shelter animals; to expanding its resources using volunteers, housing and medical protocols; and to work actively to lower the number of homeless animals entering the shelter system. Up to ten percent of animals could be killed in a no-kill shelter and still be considered a no-kill shelter.
The Malagasy giant rat, also known as the votsotsa or votsovotsa, is a nesomyid rodent found only in the Menabe region of Madagascar. It is an endangered species due to habitat loss, slow reproduction, and limited range Pairs are monogamous and females bear only one or two young per year. It is the only extant species in the genus Hypogeomys; another species, Hypogeomys australis, is known from subfossil remains a few thousand years old.
Vermin (colloquially varmint(s) or varmit(s)) are pests or nuisance animals that spread diseases and destroy crops, livestock, and property. Since the term is defined in relation to human activities, which species are included vary by region and enterprise.
Seabirds include some of the most threatened taxa anywhere in the world. For example, of extant albatross species, 82% are listed as threatened, endangered, or critically endangered by the International Union for Conservation of Nature. The two leading threats to seabirds are accidental bycatch by commercial fishing operations and introduced mammals on their breeding islands. Mammals are typically brought to remote islands by humans either accidentally as stowaways on ships, or deliberately for hunting, ranching, or biological control of previously introduced species. Introduced mammals have a multitude of negative effects on seabirds including direct and indirect effects. Direct effects include predation and disruption of breeding activities, and indirect effects include habitat transformation due to overgrazing and major shifts in nutrient cycling due to a halting of nutrient subsidies from seabird excrement. There are other invasive species on islands that wreak havoc on native bird populations, but mammals are by far the most commonly introduced species to islands and the most detrimental to breeding seabirds. Despite efforts to remove introduced mammals from these remote islands, invasive mammals are still present on roughly 80% of islands worldwide.
Cats are an invasive species in Australia. Because they are not native to Australia and were only introduced by European colonists as pets in the early 1800s, native Australian animals did not co-evolve with them. As of 2016, some 3.8 million domestic cats and up to 6.3 million feral cats continue to live in Australia.
Library cats are domesticated cats that live in public libraries worldwide. The association of cats with libraries continued from the Middle Ages up to the present day.
A ratter is any dog used for catching and killing rats and similar vermin. Specialized rat-catching breeds are found in many countries. A typical ratter is small to medium-sized and has a short and smooth coat, however a wide range of dog breeds and landraces may be used. The use of ratting dogs is widely considered to be the most environmentally friendly, humane and efficient methods of exterminating rodents. Ratting dogs are considered more efficient than domestic cats.
The Working Cats Program in Los Angeles, California, created by animal activist Melya Kaplan in 1999, is a green program that relocates sterilized and vaccinated feral cats to residences or businesses with large rat populations.
The Richmond SPCA is an idependent non-profit animal shelter in Richmond, Virginia founded in 1891.
Cat predation on wildlife is the result of the natural instincts and behavior of both feral and owned house cats to hunt small prey, including wildlife. Some people view this as a desirable phenomenon, such as in the case of barn cats and other cats kept for the intended purpose of pest control; but scientific evidence does not support the popular use of cats to control urban rat populations, and ecologists oppose their use for this purpose because of the disproportionate harm they do to native wildlife. As an invasive species and predator, they do considerable ecological damage.
Ryders Alley Trencher-fed Society (R.A.T.S.) is a New York City group founded in the 1990s that conducts organized rat catching with ratting dogs. The group was named by founding member Richard Reynolds after Ryders Alley in Manhattan, which was once rat infested, and the trencher-fed pack assembled to hunt. The group often hunts in Lower Manhattan locations like Theatre Alley where garbage is accessible to vermin.
A bodega cat is a type of working cat that inhabits a bodega, which in New York City English refers to a convenience store or deli. Much like farm cats, library cats, and ship cats, a bodega cat is typically a mixed breed cat kept as a form of biological pest control to manage or prevent rodent infestations.
