Pet adoption is the process of transferring responsibility for a pet that was previously owned by another party. Common sources for adoptable pets are animal shelters, rescue groups, or other pet owners. Some organizations give adopters ownership of the pet, while others use a guardianship model wherein the organization retains some control over the animal's future use or care.
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.
Neutering, from the Latin neuter, is the removal of a non-human animal's reproductive organ, either all of it or a considerably large part. The male-specific term is castration, while spaying is usually reserved for female animals. Colloquially, both terms are often referred to as fixing. In male horses, castrating is referred to as gelding. An animal that has not been neutered is sometimes referred to as entire or intact.
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.
Animal euthanasia is the act of killing an animal humanely, most commonly with injectable drugs. Reasons for euthanasia include incurable conditions or diseases, lack of resources to continue supporting the animal, or laboratory test procedures. Euthanasia methods are designed to cause minimal pain and distress. Euthanasia is distinct from animal slaughter and pest control.
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 zona pellucida is the specialized area surrounding mammalian oocytes (eggs). It is also known as an egg coat. The zona pellucida is essential for oocyte growth and fertilization.
In some countries there is an overpopulation of pets such as cats, dogs, and exotic animals. In the United States, six to eight million animals are brought to shelters each year, of which an estimated three to four million are subsequently euthanized, including 2.7 million considered healthy and adoptable. Euthanasia numbers have declined since the 1970s, when U.S. shelters euthanized an estimated 12 to 20 million animals. Most humane societies, animal shelters and rescue groups urge animal caregivers to have their animals spayed or neutered to prevent the births of unwanted and accidental litters that could contribute to this dynamic.
Wildlife contraceptives are contraceptives used to regulate the fertility of wild animals. They are used to control population growth of certain wild animals.
Broodstock, or broodfish, are a group of mature individuals used in aquaculture for breeding purposes. Broodstock can be a population of animals maintained in captivity as a source of replacement for, or enhancement of, seed and fry numbers. These are generally kept in ponds or tanks in which environmental conditions such as photoperiod, temperature and pH are controlled. Such populations often undergo conditioning to ensure maximum fry output. Broodstock can also be sourced from wild populations where they are harvested and held in maturation tanks before their seed is collected for grow-out to market size or the juveniles returned to the sea to supplement natural populations. This method, however, is subject to environmental conditions and can be unreliable seasonally, or annually. Broodstock management can improve seed quality and number through enhanced gonadal development and fecundity.
Culling is the process of segregating organisms from a group according to desired or undesired characteristics. In animal breeding, it is removing or segregating animals from a breeding stock based on a specific trait. This is done to exaggerate desirable characteristics, or to remove undesirable characteristics by altering the genetic makeup of the population. For livestock and wildlife, culling often refers to killing removed animals based on their characteristics, such as their sex or species membership, or as a means of preventing infectious disease transmission.
Canine reproduction is the process of sexual reproduction in domestic dogs, wolves, coyotes and other canine species.
Animal trapping, or simply trapping or ginning, is the use of a device to remotely catch an animal. Animals may be trapped for a variety of purposes, including food, the fur trade, hunting, pest control, and wildlife management.
Nuisance wildlife management is the selective removal of problem individuals or populations of specific species of wildlife. Other terms for the field include wildlife damage management, wildlife control, and animal damage control. Some wild animal species may get used to human presence, causing property damage or risking the transfer of diseases (zoonoses) to humans or pets. Many wildlife species coexist with humans very successfully, such as commensal rodents which have become more or less dependent on humans.
Alley Cat Rescue is an international nonprofit organization, headquartered in Mount Rainier, Maryland, that works to protect cats using trap–neuter–return for community cats; rescue, and neuter before adoption; promoting compassionate, non-lethal population control; and by providing national and international resources for cat caretakers.
Overpopulation or overabundance is a phenomenon in which a species' population becomes larger than the carrying capacity of its environment. This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources. The animals in an overpopulated area may then be forced to migrate to areas not typically inhabited, or die off without access to necessary resources.
The National Animal Interest Alliance (NAIA) is a non-profit organization in the United States dedicated to promoting animal welfare and animal husbandry practices, strengthening the human-animal bond, and safeguarding the rights of responsible animal owners and professionals through research, public education and public policy. The NAIA mission is "to promote the welfare of animals."
Compassion and Responsibility for Animals (CARA) is a registered non-profit, non-government animal welfare organization in the Philippines. It was founded in 2000 by a group of animal lovers determined to help the plight of animals in the Philippines. The current president of CARA is Nancy Cu-Unjieng.
A working cat is type of domestic cat that "works" for its keep by hunting vermin, such as rodents. They are commonly employed where pest control is needed, such as barns, farms, factories, warehouses, stores, churchyards, and private property. Types of working cats include the bodega cat, farm cat, ship's cat, and library cat. A benefit of using a working cat is that they alleviate the need for harmful pesticides. Working cats are often placed in their environment as a part of a working cats program.
In biology, overabundant species refers to an excessive number of individuals and occurs when the normal population density has been exceeded. Increase in animal populations is influenced by a variety of factors, some of which include habitat destruction or augmentation by human activity, the introduction of invasive species and the reintroduction of threatened species to protected reserves.
