This study recovered mitochondrial genomes from the extinct scimitar-toothed cat Homotherium using ancient DNA, including a specimen from the permafrost, to place the sabertooths relative to living ca…

Complementing maternally inherited mitochondrial DNA, Y-chromosome markers trace paternal lineages and reveal male-specific patterns of dispersal and mating in cats. This overview surveys how feline Y…

Recovering DNA from extinct cats and historical museum specimens requires specialized techniques to cope with degraded, fragmented, and contaminated genetic material. This overview surveys how researc…

Conservation managers must decide which populations to treat as separate units for protection, breeding, and translocation, and genetics provides the primary evidence. This overview surveys the concep…

In many cats, one sex disperses farther than the other, with males typically moving while females remain near their natal range, a pattern that leaves distinct genetic footprints. This overview survey…

The end of the Pleistocene saw the loss of many large cats, including sabertooths, cave lions, American lions, and the American cheetah, as part of the broader megafaunal extinction. This overview sur…

Small or isolated cat populations frequently show the hallmarks of inbreeding depression, including reduced fertility, abnormal sperm, congenital defects, weakened immunity, and elevated juvenile mort…

The major histocompatibility complex encodes immune-recognition molecules whose diversity is crucial for resisting pathogens, and its depletion is a key concern in inbred cat populations. This overvie…

Before genome sequencing became routine, microsatellites, short tandem repeats scattered through the genome, were the workhorse markers of felid population and forensic genetics. This overview surveys…

Mitochondrial DNA, with its maternal inheritance, high copy number, and relatively fast evolution, was central to the first molecular phylogenies and phylogeographic studies of cats. This overview sur…

Estimating when cat lineages diverged requires calibrating molecular substitution rates against the fossil record, a process fraught with uncertainty when fossils are sparse. This overview surveys how…

Natural history museum collections preserve specimens spanning centuries, providing a genetic archive of felid populations as they existed before recent declines. This overview surveys how museum geno…

Habitat loss and fragmentation increasingly isolate cat populations into small patches separated by inhospitable terrain, reducing effective population size and gene flow. This overview surveys how co…

Since the first lightly sequenced domestic cat genome, feline genomics has advanced to highly contiguous, chromosome-level assemblies for the domestic cat and an expanding set of wild species. This ov…

Modern cats are divided into eight monophyletic lineages: the Panthera lineage (lions, tigers, leopards, jaguars, snow leopards, clouded leopards), the bay cat lineage, the caracal lineage, the ocelot…

Cats are obligate carnivores, physiologically dependent on a meat diet, and comparative genomics has uncovered the molecular underpinnings of this specialization. This overview surveys findings that f…

The modern cats diversified into roughly forty species within the last eleven million years, a relatively rapid radiation that left a tangled phylogeny marked by short internal branches. This overview…

Genetic tools are increasingly used to combat the illegal trade in cats and their parts, from tiger bones and skins to confiscated live animals. This overview surveys how forensic genetics assigns sei…

This landmark study reconstructed the evolutionary tree of all 37 living cat species using mitochondrial and nuclear DNA sequences combined with molecular dating calibrated by the fossil record. The a…
