Inheritance of the catnip response in domestic cats
PaperThis early genetic study examined the familiar but variable reaction of cats to catnip and proposed that responsiveness is an inherited trait. By observing the catnip response across cats and consider…

Major taste loss in carnivorous mammals
PaperThis comparative study examined taste-receptor genes across a range of carnivorous mammals and found widespread loss of taste capabilities tied to diet. Building on the earlier discovery that cats lac…

Pseudogenization of a sweet-receptor gene accounts for cats' indifference to sugar
PaperThis landmark genetic study explained the long-noted fact that cats show little interest in sweet foods. The researchers found that cats carry a defective, non-functional version of Tas1r2, one of the…

Research overview: age-related hearing loss in senior cats
OverviewAs cats age, many experience a decline in hearing, a feline counterpart to the presbycusis seen in aging humans. This overview surveys age-related hearing loss in senior cats, which can reduce sensiti…
Research overview: aiming the pinnae to localize prey
OverviewWhen hunting by ear, a cat actively orients its pinnae toward a sound source to maximize gain and sharpen localization before striking. This overview surveys how pinna aiming integrates with the broad…
Research overview: allorubbing and shared scent among cats
OverviewWhen cats rub against each other, a behavior called allorubbing, they mingle their scents and may create a shared group odor. This overview surveys allorubbing and related allomarking behaviors, in wh…
Research overview: amino-acid taste preferences and feline food selection
OverviewCats evaluate food partly through the tastes of specific amino acids, which signal protein content and palatability. This overview surveys how feline taste preferences are shaped by amino acids, with…
Research overview: anal sac secretions in feline scent signaling
OverviewCats possess paired anal sacs that produce a strongly scented secretion thought to contribute to individual odor identity and communication. This overview surveys what is known about these secretions,…
Research overview: arrangement of the mystacial whiskers
OverviewThe prominent whiskers on a cat's muzzle, the mystacial vibrissae, are arranged in an orderly grid of rows and columns on each side of the face. This overview surveys their typical number and layout,…
Research overview: auditory development in kittens
OverviewNewborn kittens cannot hear well because their ear canals are closed at birth, and hearing develops over the following weeks. This overview surveys feline auditory development, beginning with the open…
Research overview: behavioral measures of feline olfactory acuity
OverviewBeyond anatomy and genetics, behavioral tests reveal how keenly cats can detect and discriminate odors. This overview surveys studies and observations of feline olfactory acuity, including the use of…
Research overview: behavioral tests of color discrimination in cats
OverviewEstablishing that an animal sees color requires showing it can discriminate hues independent of brightness, a demanding behavioral test. This overview surveys studies that trained cats to choose color…
Research overview: binaural cues and interaural comparisons in cats
OverviewLocalizing sound in the horizontal plane depends on comparing the signals reaching the two ears, and cats exploit these binaural cues effectively. This overview surveys interaural time and level diffe…
Research overview: biomechanics of the cat's mid-air righting maneuver
OverviewThe physics of how a falling cat rights itself without any initial rotation has fascinated scientists for over a century. This overview surveys the biomechanics of the maneuver, in which the cat bends…
Research overview: bitter sensitivity and avoidance of harmful substances
OverviewA common interpretation of bitter taste is that it warns animals away from toxic or harmful compounds, and this protective role likely applies to cats. This overview surveys how feline bitter sensitiv…
Research overview: bitter taste receptors in the domestic cat
OverviewCats retain the ability to taste bitter compounds, supported by a family of bitter taste receptor genes. This overview surveys what is known about the feline bitter receptor repertoire and its likely…
Research overview: carpal whiskers on the feline foreleg
OverviewIn addition to facial whiskers, cats possess carpal vibrissae on the underside of the wrists, or carpi, of the forelegs. This overview surveys these lesser-known tactile hairs and their proposed role…
Research overview: cauxin and the production of felinine in cat urine
OverviewThe amount of felinine in cat urine is regulated in part by an enzyme called cauxin, which is excreted in the urine and influences the production of this scent precursor. This overview surveys the rol…
Research overview: central integration of whisker and visual signals
OverviewTactile information from the whiskers is integrated with other senses in brain regions that coordinate orienting and targeting, including midbrain structures involved in directing attention and moveme…
Research overview: changes in taste and food acceptance with age
OverviewAs cats age, their perception of taste, together with smell, can change in ways that affect food acceptance. This overview surveys age-related changes in feline taste and their interaction with declin…
Research overview: comparative tapetum structure across carnivores
OverviewThe tapetum lucidum is widespread among nocturnal and crepuscular vertebrates, but its structure varies, and comparing forms illuminates how cats fit the broader pattern. This overview surveys differe…
Research overview: comparing cat and human performance in dim light
OverviewHow much better do cats really see in the dark than people? This overview surveys behavioral and physiological comparisons, which generally credit cats with the ability to detect light at intensities…
Research overview: comparing feline and canine olfactory gene counts
OverviewDogs are famed for their sense of smell, and comparing them with cats puts feline olfaction in perspective. This overview surveys estimates that cats possess a large but somewhat smaller repertoire of…
Research overview: comparing silver vine and catnip responses
OverviewSilver vine and catnip both elicit the characteristic feline rubbing and rolling response, but they differ in potency and in which cats they affect. This overview surveys comparisons showing that silv…
Research overview: critical periods in the developing feline visual cortex
OverviewThe kitten visual cortex has a critical period during which experience strongly shapes its wiring, a concept established largely through feline research. This overview surveys the idea of the critical…
Research overview: dark adaptation in the feline visual system
OverviewDark adaptation is the process by which an eye recovers sensitivity after exposure to bright light, as pigment regenerates and neural gain rises. This overview surveys what is known about the time cou…
Research overview: declining olfaction and appetite in aging cats
OverviewA cat's sense of smell can diminish with age, and because olfaction strongly influences feline appetite, this decline can affect eating. This overview surveys age-related changes in feline olfaction a…
Research overview: depth-of-field and blur cues from the slit pupil
OverviewAmbush predators must judge the distance to prey accurately before striking, and pupil shape can influence the depth cues available. This overview surveys the proposal that vertical-slit pupils create…
Research overview: detecting air currents with feline whiskers
OverviewWhiskers respond not only to direct contact but to subtle movements of air, allowing cats to sense nearby objects and motion without touching them. This overview surveys how vibrissae detect air curre…
