Abstract

Significance: We present highlights of the first complete domestic cat reference genome, to our knowledge. We provide evolutionary assessments of the feline protein-coding genome, population genetic discoveries surrounding domestication, and a resource of domestic cat genetic variants. These analyses span broadly, from carnivore adaptations for hunting behavior to comparative odorant and chemical detection abilities between cats and dogs. We describe how segregating genetic variation in pigmentation phenotypes has reached fixation within a single breed, and also highlight the genomic differences between domestic cats and wildcats. Specifically, the signatures of selection in the domestic cat genome are linked to genes associated with gene knockout models affecting memory, fear-conditioning behavior, and stimulus-reward learning, and potentially point to the processes by which cats became domesticated.

TL;DR

This paper presents a high-quality domestic cat reference genome (FelCat5) and comparative genomic analyses identifying signatures of selection related to carnivory, sensory biology, and domestication. It also reports two recessive KIT missense mutations associated with the Birman gloving pigmentation pattern.

Key findings

  • The FelCat5 assembly comprises 2.35 Gb assigned to all 18 autosomes and the X chromosome, plus 11 Mb in unplaced scaffolds, with an N50 contig of 20.6 kb and scaffold N50 of 4.7 Mb; the cat genome is predicted to contain 19,493 protein-coding genes and 1,855 noncoding RNAs.
  • Genome-wide dN/dS analyses identified 467, 331, and 281 genes putatively under positive selection in the carnivore, felid, and domestic cat (Felinae) ancestral lineages, respectively; Felinae positively selected genes were enriched for lipid metabolism, and sensory genes included vision and hearing candidates.
  • Cats and dogs show an evolutionary tradeoff in chemosensory repertoires: felids have smaller functional olfactory receptor repertoires (~700 genes) than dogs (>800), while the vomeronasal V1r repertoire is reduced in dogs (8 functional genes) but expanded in the cat ancestor (21 functional genes).
  • Domestication analyses found 130 autosomal regions with pooled heterozygosity 4 SDs below the mean or FST greater than 4 SDs from the mean; five high-confidence regions contained neural/neural-crest-related genes (reported as 13 genes in Results and 12 known genes in Fig. 3/conclusion). For Birman gloving, two adjacent KIT exon 6 missense mutations were concordant with the phenotype; all 150 Birman cats genotyped were homozygous for both SNPs, and the Birman gloving haplotype frequency was 12.3% in Ragdoll and 10% in the random nonbreed population.

Methods

  • A female Abyssinian cat (“Cinnamon”) provided DNA for ~14× whole-genome shotgun coverage using Sanger and 454 technology; a BAC library was constructed and end-sequenced, and sequences were assembled with CABOG.
  • Selection analyses used 10,317 sets of 1:1:1:1:1 orthologs from human, cow, dog, tiger, and domestic cat, with PAML 4.0 branch and branch-site models, TreeSAAP and PROVEAN for amino acid impact, and WebGestalt for functional enrichment.
  • Domestication scans used pooled resequencing of 22 domestic cats from six breeds (~58× coverage) and a wildcat pool of two European and two Near Eastern wildcats (~7× coverage); SNVs were called with SAMtools, VarScan 2, and PoPoolation2, and 100-kb windows with 50-kb step were tested for low Hp and high FST. KIT exons were resequenced/genotyped in 409 cats from 21 breeds, 5 Birman outcrosses, and 315 random bred cats, with a larger sample of 150 Birman cats and 729 additional cats.

Limitations

  • The paper states that the selection inferences “call for additional functional analyses,” so most positively selected genes are computational candidates rather than experimentally validated.
  • The paper notes cats are considered only semidomesticated, with ongoing admixture with wildcats, a relatively short cohabitation history, and limited isolation from wild populations, which may explain the modest number of strong domestication signals.
  • Evident from the text: domestication scans rely on pooled sequencing and pooled breed samples, the wildcat comparison uses only four individuals at ~7× coverage, and the reported gene count in the five high-confidence regions differs between the Results (13 genes) and Fig. 3/conclusion (12 known genes).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
