Research overview: detecting mouse ultrasonic vocalizations
OverviewMice communicate using ultrasonic vocalizations well above the human hearing range, and these calls fall squarely within what cats can detect. This overview surveys the intersection of rodent ultrason…
Research overview: development of the tapetum lucidum in kittens
OverviewThe reflective tapetum is not fully mature at birth, and its development parallels the broader maturation of the kitten visual system. This overview surveys what is known about how the tapetum forms a…
Research overview: developmental onset of the catnip response
OverviewThe familiar reaction to catnip does not appear until a kitten is several months old, making it a developmentally timed sensory behavior. This overview surveys the onset of the catnip response, which…
Research overview: directional gain and sound collection by the feline ear
OverviewThe funnel shape of the cat's pinna collects sound and boosts sensitivity in the direction it faces, providing directional acoustic gain. This overview surveys how the pinna concentrates sound energy…
Research overview: ear movements as indicators of feline attention
OverviewA cat's ears reveal where its attention lies, swiveling toward sounds of interest even when the head and eyes are still. This overview surveys how ear orientation serves as a readout of auditory atten…
Research overview: ear position in feline visual communication
OverviewBeyond their auditory role, the highly mobile feline ears are an important channel of visual communication. This overview surveys how ear position signals emotional state, with upright forward ears in…
Research overview: early whisker and tactile development in kittens
OverviewTouch is one of the earliest functional senses in kittens, and the whisker system is important from the beginning of life. This overview surveys early tactile and whisker development in kittens, which…
Research overview: electrophysiology of feline cones and color pathways
OverviewElectroretinography and single-cell recording have been used to probe how the cat retina responds to different wavelengths, providing physiological evidence about color processing. This overview surve…
Research overview: eye opening and early visual development in kittens
OverviewKittens are born with their eyes closed and acquire functional vision gradually over the first weeks of life. This overview surveys the timeline of feline visual development, beginning with the eyes o…
Research overview: facial and cheek gland pheromones in cats
OverviewCats have scent glands on the face, including around the cheeks, chin, and lips, that deposit pheromones when the cat rubs its head against objects, people, or other cats. This overview surveys these…
Research overview: feline cochlear structure and frequency encoding
OverviewThe cochlea is the inner-ear structure that converts sound into neural signals, and its mechanics set the frequency range an animal can hear. This overview surveys what is known about the feline cochl…
Research overview: feline dichromacy and the limits of cat color vision
OverviewCats are generally understood to be dichromats, possessing two functional cone types rather than the three that give humans full color vision. This overview surveys behavioral and physiological eviden…
Research overview: feline sensitivity to ultrasonic rodent calls
OverviewMice and other rodents produce vocalizations and movement sounds that extend into ultrasonic frequencies inaudible to humans, and cats are well equipped to hear them. This overview surveys how the cat…
Research overview: feline sweet blindness and obligate carnivory
OverviewCats famously fail to respond to sweet tastes, and this trait is rooted in their genetics and diet. This overview surveys the phenomenon of feline sweet blindness, in which cats lack a functional swee…
Research overview: feline vibrissae and the sense of touch
OverviewWhiskers, or vibrissae, are specialized tactile hairs that give cats a high-resolution sense of touch crucial for navigation and hunting. This overview surveys the types and distribution of feline vib…
Research overview: felinine and sulfur compounds as feline scent signals
OverviewCat urine contains felinine, an amino-acid-derived compound that breaks down into volatile sulfur-containing molecules responsible for the strong odor of cat marks. This overview surveys the role of f…
Research overview: flank, tail, and other body gland marking in cats
OverviewBeyond the face and paws, cats have scent glands on other parts of the body, including along the tail and flanks, that contribute to chemical marking. This overview surveys these additional glandular…
Research overview: flicker fusion and motion detection in cats
OverviewCats are exquisitely sensitive to movement, and their temporal vision, including the rate at which flickering light fuses into a steady image, shapes how they perceive motion. This overview surveys fe…
Research overview: forward-facing eyes, stereopsis, and the slit pupil
OverviewCats have forward-facing eyes with substantial binocular overlap, giving them stereoscopic depth perception that complements any depth cues from pupil shape. This overview surveys how binocular vision…
Research overview: frequency discrimination in cats
OverviewBeyond detecting sounds, cats can discriminate between tones of different pitch, a capacity studied through behavioral and physiological methods. This overview surveys feline frequency discrimination,…
Research overview: head stabilization during feline locomotion
OverviewAs a cat moves, it tends to hold its head steady, stabilizing the platform on which its eyes and inner ears sit. This overview surveys head stabilization during locomotion, in which vestibular and vis…
Research overview: hearing, white coats, and congenital deafness in cats
OverviewA well-known link in feline sensory biology connects white coat color, blue eyes, and congenital deafness. This overview surveys the association between the dominant white gene and inner-ear degenerat…
Research overview: heritability and prevalence of the catnip response
OverviewNot all cats respond to catnip, and the trait appears to be inherited. This overview surveys evidence that responsiveness to catnip is governed by genetics, with roughly two-thirds of cats showing the…
Research overview: high-rise syndrome and falls in cats
OverviewCats sometimes fall from windows and balconies, and veterinary observations of these incidents, sometimes called high-rise syndrome, have produced counterintuitive findings. This overview surveys repo…
Research overview: how the tapetum trades acuity for sensitivity
OverviewReflecting light back through the retina improves sensitivity but also scatters photons, slightly degrading the sharpness of the image. This overview surveys discussion of that tradeoff in cats, where…
Research overview: hunting by sound in the domestic cat
OverviewCats frequently locate and strike at prey they cannot see, relying on hearing to guide the attack. This overview surveys how acute sound localization and broad, high-reaching hearing enable cats to hu…
Research overview: independent rotation of the feline pinnae
OverviewEach of a cat's ears can move independently, allowing it to monitor two directions at once or to converge both ears on a single sound. This overview surveys the behavioral and functional significance…
Research overview: individual chemical signatures in cats
OverviewEach cat may carry a distinctive chemical signature encoded in its scent marks and body odor, allowing other cats to recognize individuals. This overview surveys the idea that the mixture of compounds…
Research overview: interdigital glands and scratch marking
OverviewWhen cats scratch surfaces, they leave more than visible marks; scent glands between the toes deposit chemical signals as well. This overview surveys the role of interdigital, or paw, glands in scent…
