Hosey proposed a conceptual model of how relationships form between zoo animals and the humans around them, distinguishing the effects of unfamiliar visitors from those of familiar keepers. He argued…

Miller and colleagues proposed that the diversity of behaviours an animal performs, not just the presence or absence of specific behaviours, can serve as an indicator of positive welfare, with higher…

Watters, Margulis and Atsalis advocated systematic, ongoing behavioural monitoring of individual zoo animals as a foundation for evidence-based husbandry. They described how regularly recording behavi…

Clubb and Mason analysed comparative data across 35 carnivore species to ask why some thrive in zoos while others pace and breed poorly. They found that wide-ranging species with large natural home ra…

Skibiel, Trevino and Naugher systematically compared categories of enrichment, including food-based items, spices and scents, and novel objects, for captive cats to see which most effectively boosted…

Donadio and Buskirk tested what predicts the intensity of interactions among carnivores, including both killing and avoidance. Analyzing a broad dataset, they found that intraguild predation and aggre…

Margulis, Hoyos and Anderson examined the relationship between how active captive cats are and how long visitors watch them. Observing several felid species, they found that visitor interest, measured…

This study documented the first confirmed natural SARS-CoV-2 infections in big cats, occurring in tigers and lions at the Bronx Zoo early in the COVID-19 pandemic. After several cats developed respira…

McPhee tested whether feeding whole, intact carcasses rather than processed meat changes the behaviour of large captive cats. Providing carcasses increased feeding-related and active behaviours and al…

Palomares and Caro compiled and analyzed the global record of carnivores killing other carnivores, establishing intraguild predation as a widespread structuring force. They showed that interspecific k…

Creel and Creel demonstrated that African wild dog populations are limited not by prey scarcity but by competition with lions and spotted hyenas, which kill dogs and steal their kills. Analyzing demog…

Mellor elaborated the Five Domains Model, which structures welfare assessment around four physical and functional domains, nutrition, environment, health and behaviour, that feed into a fifth, the ani…

Challenging the assumption that FIV is harmless in its natural hosts, this study examined wild African lions for clinical and pathological signs associated with feline immunodeficiency virus infection…

Sinclair, Mduma and Brashares tested why some Serengeti ungulate species are regulated by predation while others are limited by food, using long-term data across the migratory and resident herbivore c…

Owen-Smith and Mills assembled a detailed predation web for Kruger National Park, quantifying which predators kill which prey and in what proportions across the size spectrum. They mapped how lion, le…

This study compared the outbred Serengeti lion population with the small, geographically isolated Ngorongoro Crater population, which descended from few founders and experienced inbreeding. The author…

This overview synthesizes telemetry research on African lion movement and pride ranging, drawing on long-term projects such as the Oxford-led study in and around Hwange National Park, Zimbabwe. GPS co…

Lentiviruses related to domestic-cat FIV circulate widely in wild felid species including lions, pumas, leopards, and others, often at high seroprevalence yet apparently with limited disease in their…

Gonadotropin-releasing hormone agonist implants offer a reversible method of suppressing reproduction in cats by downregulating the reproductive axis after an initial stimulation. This overview survey…

Hepatozoon is a tick-associated protozoan parasite, transmitted not by tick bite but by ingestion of infected ticks, that commonly infects wild felids including lions. This overview surveys the biolog…

Many of the most important felid diseases, from distemper to leukemia virus to Toxoplasma, originate at the interface of domestic animals, wildlife and people, making them quintessential One Health pr…

Following the Bronx Zoo tigers, SARS-CoV-2 infections were confirmed in big cats at zoos and sanctuaries across multiple countries, including additional tigers, lions, snow leopards, pumas and others.…

Sarcocystis parasites cycle between predator definitive hosts and prey intermediate hosts, with felids shedding infective stages after eating cysts in muscle. This overview surveys the role of wild ca…

Spirometra tapeworms use felids and other carnivores as definitive hosts, while their larval stages, known as spargana, infect a wide range of intermediate and paratenic hosts, including amphibians, r…

Toxocara cati and related ascarid roundworms are among the most common parasites of cats, with wild felids shedding eggs that contribute to environmental contamination and pose a zoonotic risk to peop…

Serosurveys consistently reveal high Toxoplasma exposure in wild felids, reflecting their role as both definitive hosts and predators of infected prey. This overview synthesizes prevalence patterns ac…

African lions and other wild felids can be infected with Trypanosoma, tsetse-transmitted protozoan parasites better known for causing sleeping sickness in humans and nagana in livestock. This overview…
