What should I note about the scientific name of the cat?

Felis catus (domestic cat). The actual judgement still rests with a veterinarian on a case-by-case basis, and this article gives no drug names or dosages.

What should I note about the lifespan range of the cat?

Lifespan: ① life expectancy at birth = 11.18 years (US Banfield clinic data, Montoya et al., PMC9989186, "life expectancy at birth...11.18 years (11.16–11.20) for cats" , verified 2026-07-30) ② median age-at-death = 14.0 years (UK 2009–2012 study, cited in the same paper, "median age-at-death of cats between 2009 and 2012 in a UK study was 14.0 years", verified 2026-07-30). ⚠️ The two estimators must not be combined: their denominators and sampling are entirely different. State which one you are citing. (OP construct correction 2026-07-30: a CX audit caught the statistical constructs as mismatched; the two studies use different methodologies — the former is a life-expectancy-at-birth statistic, the latter a median age at death, and the numbers are not interchangeable). The actual judgement still rests with a veterinarian on a case-by-case basis, and this article gives no drug names or dosages.

What should I note about the life-stage classification of the cat?

Kitten / junior / adult / mature / senior; the age boundaries for each stage follow the 2021 AAHA/AAFP Feline Life Stage Guidelines (catvets.com: "Kitten: birth up to 1 year" "Young adult: 1 to 6 years" "Mature adult: 7 to 10 years" "Senior: 10 years and older" "End-of-life: any age", , verified 2026-07-30); ⚠️ the 2021 edition has been simplified to 4 age stages plus an end-of-life stage, which does not map exactly onto the older 5-stage naming used in this table; take the age cut-points from the newer edition. The actual judgement still rests with a veterinarian on a case-by-case basis, and this article gives no drug names or dosages.

The full content of the "breeds and lifespan" column in the 12-column knowledge tree for cats. Where the original text could not obtain an authoritative figure for a field, it leaves the field blank and states why; this site preserves that as-is and does not fill in numbers on its behalf. The disease column has been published separately as vet/cat-common-diseases and is not duplicated here.

Cats | Breeds and Lifespan

This article is compiled from the cat section of the veterinary encyclopedia. The same symptom calls for different handling in different species, and following another species' approach can be harmful — first confirm which animal you are dealing with.

Item	Content
Scientific name	Felis catus (domestic cat)
Lifespan range	Lifespan: ① life expectancy at birth = 11.18 years (US Banfield clinic data, Montoya et al., PMC9989186, "life expectancy at birth...11.18 years (11.16–11.20) for cats" <https://pmc.ncbi.nlm.nih.gov/articles/PMC9989186/>, verified 2026-07-30) ② median age-at-death = 14.0 years (UK 2009–2012 study, cited in the same paper, "median age-at-death of cats between 2009 and 2012 in a UK study was 14.0 years", verified 2026-07-30). ⚠️ The two estimators must not be combined: their denominators and sampling are entirely different. State which one you are citing. (OP construct correction 2026-07-30: a CX audit caught the statistical constructs as mismatched; the two studies use different methodologies — the former is a life-expectancy-at-birth statistic, the latter a median age at death, and the numbers are not interchangeable); the average lifespan gap between indoor-kept cats and cats with free outdoor access 【no single authoritative value for this item: the whitelist sources provide no cat-specific reference value for the indoor–outdoor lifespan gap in years; the PMC paper above only notes qualitatively that "outdoor access poses a greater risk of road traffic accidents" and "An indoor lifestyle is associated with feline obesity", giving no quantified difference in years; separately, the non-whitelist blog catcareworld.com was found claiming to cite a "2023 JAVMA study, n=4,206, indoor lifespan 3.2× that of outdoor cats", which a direct PubMed check found no such publication for, so it was judged a suspected fabricated citation and excluded, 2026-07-30; the direction is clear: cats with outdoor access are markedly shorter-lived because of road accidents, infectious disease and fighting, but no authoritative page giving the precise difference in years could be found】
Life-stage classification	Kitten / junior / adult / mature / senior; the age boundaries for each stage follow the 2021 AAHA/AAFP Feline Life Stage Guidelines (catvets.com: "Kitten: birth up to 1 year" "Young adult: 1 to 6 years" "Mature adult: 7 to 10 years" "Senior: 10 years and older" "End-of-life: any age", <https://catvets.com/resource/aaha-aafp-feline-life-stage-guidelines/>, verified 2026-07-30); ⚠️ the 2021 edition has been simplified to 4 age stages plus an end-of-life stage, which does not map exactly onto the older 5-stage naming used in this table; take the age cut-points from the newer edition
Body-type classification	Shorthair / longhair; oriental type (slender) / cobby type (e.g. Persian); brachycephalic / normal muzzle / long muzzle
Phenotype–health links	White coat with blue eyes is associated with congenital deafness (not confined to a single breed); brachycephaly = airway problems and epiphora; folded ears and short legs = skeletal developmental abnormalities; hairlessness = thermoregulation and sebum issues

Hereditary disease reference for purebred cats (15 breeds)

⚠️ The disease-to-breed associations in this table are a directional summary; gene names and test names are all marked 【conceptual description, not a specific publication — 🚫: "genetic testing" is a generic term, not a specific publication or test name】 (they need to be checked against current testing-laboratory listings); breed-specific prevalence 【verification result: no single authoritative value — breed-specific genetic disease prevalence varies enormously by population, region and breeding stock, and no single cross-population percentage attributable to a whitelist source was found; citing unverified percentages is prohibited, 2026-07-30】. Having a test available does not mean the disease will necessarily occur.

Breed	Main hereditary / breed-associated diseases	Screening or monitoring direction
Persian	Polycystic kidney disease (PKD); brachycephalic syndrome (breathing, epiphora, dental crowding); progressive retinal atrophy; dystocia	Renal ultrasound + genetic testing 【conceptual description, not a specific publication — 🚫: "genetic testing" is a generic term, not a specific test name; check against current testing-laboratory listings】; ophthalmology
Exotic Shorthair	Same as Persian (shared breeding origin)	Same as Persian
Himalayan	Same as Persian; PKD	Same as Persian
Maine Coon	Hypertrophic cardiomyopathy (HCM); hip dysplasia; spinal muscular atrophy	Regular echocardiographic follow-up + HCM-related genetic testing 【conceptual description, not a specific publication — 🚫: as above, a generic term rather than a specific test name】
Ragdoll	HCM	As above
British Shorthair	HCM; PKD; blood-type distribution raises the risk of neonatal isoerythrolysis	Echocardiography; blood-type matching before breeding
Abyssinian	Pyruvate kinase deficiency; progressive retinal atrophy; amyloidosis (renal)	Genetic testing 【conceptual description, not a specific publication — 🚫: as above】; ophthalmology; renal function follow-up

Oriental Shorthair	Same disease group as the Siamese	As above
Scottish Fold	Osteochondrodysplasia — linked to the same gene as the folded ear, causing deformity of weight-bearing joints and caudal vertebrae and chronic pain (a major animal-welfare controversy)	Imaging assessment; lifelong pain management; breeding for this phenotype is not recommended
Munchkin	Short-leg-related skeletal abnormalities (spine, sternum, joint loading)	Imaging; weight control
Sphynx	HCM; congenital myopathy; sebum and skin infections; poor thermoregulation	Echocardiography; skin care; keeping warm
