🧬 The Felid Wiki — 3,000 research summaries

Hung carcasses and bungee-suspended food are used to encourage captive cats to pull, leap and feed in physically demanding, naturalistic ways. This overview surveys studies that pair such feeding enri…

Small, closed captive populations risk losing genetic diversity, raising the chance that deleterious recessive alleles pair up and reduce health, fertility and survival, a phenomenon known as inbreedi…

No single indicator captures welfare reliably, so the field has moved toward integrated assessment combining multiple lines of evidence. This overview surveys how comprehensive welfare evaluation for…

Degenerative joint disease is extremely common in older cats, both domestic and exotic, yet often under-recognised because cats mask pain. This overview surveys how osteoarthritis is detected and mana…

Modern exhibit design aims to provide not just naturalistic appearance for visitors but genuine behavioural opportunity for animals. This overview surveys principles of felid exhibit design: complex,…

Feeding captive non-domestic cats well requires meeting obligate-carnivore requirements for taurine, arginine, vitamin A, arachidonic acid and appropriate calcium-to-phosphorus ratios, which whole pre…

Because cats rely heavily on smell for hunting, social communication and exploring their world, scent-based enrichment is a natural fit for felid welfare. This overview surveys studies adding novel od…

Individual cats differ consistently in boldness, fearfulness, aggressiveness and sociability, and these stable traits affect welfare, breeding success and how animals respond to husbandry. This overvi…

Operant conditioning with positive reinforcement underpins modern husbandry training, allowing cats to cooperate in shifting, crating, weighing and medical procedures. This overview surveys the learni…

Play, especially object play that mimics hunting, is both an indicator and a contributor to good welfare in cats, and its absence can signal stress or poor environments. This overview surveys research…

How keepers interact with dangerous captive carnivores spans a spectrum from free contact, sharing space with the animal, to protected contact, where a barrier always separates human and cat. This ove…

Qualitative Behaviour Assessment asks trained observers to score the expressive demeanour of an animal, capturing emotional qualities such as relaxed, tense, content or frustrated that quantitative et…

Deciding when a chronically ill or aged big cat's welfare no longer justifies continued life is among the most difficult tasks in captive felid care. This overview surveys structured quality-of-life a…

As public attitudes and laws have turned against using big cats in circuses, film and other entertainment, retiring these animals to lifetime care has become a significant welfare undertaking. This ov…

Rotational exhibit systems allow multiple species or individuals to take turns occupying a series of connected spaces, multiplying the effective territory and novelty available to each animal. This ov…

The surfaces captive cats stand, walk and rest on affect comfort, health and behaviour, yet substrate is easily overlooked. This overview surveys substrate welfare for felids: the problems of hard, ab…

Familiar keepers occupy a special place in a captive animal's social environment, and the quality of the keeper-animal relationship can influence stress, cooperation and welfare. This overview surveys…

This overview surveys how the presence and behaviour of visitors specifically affect captive cats, a group that frequently responds to crowds with vigilance, hiding or altered activity. It examines st…

Felid species span tropical jungles, deserts and high mountains, so meeting their thermal needs in captivity, often in non-native climates, is a real welfare challenge. This overview surveys thermal w…

Moving cats between institutions for breeding, rescue or management is a recognised acute stressor with welfare implications. This overview surveys the science of felid transport and transfer: the str…

Non-invasive cortisol metabolite monitoring lets keepers test whether husbandry changes actually reduce physiological stress, moving welfare management from intuition to evidence. This overview survey…

Faecal glucocorticoid metabolite monitoring is the workhorse of felid stress research because it avoids the confound of capture and restraint, but it requires species-specific validation to be meaning…

Cats are arboreal-capable, climbing predators that value height, and research consistently shows captive felids prefer and benefit from elevated resting platforms, climbing structures and visually com…

Conceptual frameworks structure how we judge captive animal welfare, and they have evolved over time. This overview surveys the progression from the Five Freedoms, freedom from hunger, discomfort, pai…

This edited volume brought together early scientific work on environmental enrichment, consolidating it into a coherent field. Chapters covered the history, theory, design and evaluation of enrichment…

Wells reviewed how stimulating the senses, through olfactory, auditory, visual and tactile inputs, can enrich captive animals. She summarised evidence that scents such as spices and prey odours, sound…

Morgan and Tromborg comprehensively reviewed the environmental factors that stress captive animals, cataloguing sound, light, odour, temperature, substrate, restraint, human presence, predictability a…

Lyons, Young and Deag surveyed multiple felid species across enclosures differing in size, complexity and feeding routine to identify what most affects behaviour. They found that enclosure usage and a…

Shepherdson, Carlstead, Mellen and Seidensticker tested whether changing how food is presented could enrich the behaviour of small captive cats. Instead of single predictable meals, they provided food…

Bashaw, Bloomsmith, Maple and Bercovitch tested whether feeding-based enrichment changes behaviour in tigers and lions, comparing a hung carcass-like 'fishing' device and bones against standard feedin…
