--- title: "domestic cat vs ostrich — size, speed and bite force" description: "domestic cat and ostrich compared on mass, length, speed, bite force and lifespan — every measure side by side, with why the numbers cannot settle an encounter." url: https://atoneplace.net/animal-vs/domestic-cat-vs-ostrich/ site: "At One Place" --- # domestic cat vs ostrich **domestic cat vs ostrich: ostrich leads on 4 of 4 measures** Measured comparison — not a prediction The domesticated cat, kept worldwide and still an efficient small predator. The largest and fastest bird, laying eggs that weigh about 1.4 kg each. On the measurements below, ostrich leads on more of them — but they do not all point the same way, and the ones that disagree are the interesting part. ## The measurements | | domestic cat | ostrich | | --- | --- | --- | | Mass | 3.6–6.8 kg | 63–156 kg | | Length | 0.36–0.55 m | — | | Height | 0.23–0.3 m | 1.7–2.8 m | | Top speed | 48 km/h | 60–70 km/h | | Lifespan | 12–20 yr | 30–50 yr | ## Where each one leads - Mass: ostrich is 24× heavier. - Height: ostrich is 9.6× taller. - Top speed: ostrich is 1.5× faster. - Lifespan: ostrich is 2.7× a longer life. ## What this does and does not tell you These are measured averages with real ranges behind them, and every figure links to its own page. What they cannot do is settle an encounter. Outcomes between animals turn on circumstance — who initiates, whether either is hungry, defending young, injured or cornered, and what the terrain favours. Size and bite force are not decisive on their own, and most of these pairs never meet in the wild in any case, because their ranges do not overlap. > Every figure here is an average with a substantial spread. Individual animals vary enormously — a large individual of the smaller species routinely exceeds a small individual of the larger one. ## Common questions ### Is a domestic cat bigger than a ostrich? ostrich is heavier — 63–156 kg against 3.6–6.8 kg. ### Who would win, a domestic cat or a ostrich? That is not something measurements can settle. The comparison above shows which animal leads on each measure, but an actual encounter depends on circumstance, motivation, health and terrain — and most pairs like this never meet in the wild. ## Related pages - [How much does a domestic cat weigh?](https://atoneplace.net/weight/domestic-cat/) - [How much does a ostrich weigh?](https://atoneplace.net/weight/ostrich/) - [lion vs ostrich](https://atoneplace.net/animal-vs/lion-vs-ostrich/) - [leopard vs ostrich](https://atoneplace.net/animal-vs/leopard-vs-ostrich/) - [jaguar vs ostrich](https://atoneplace.net/animal-vs/jaguar-vs-ostrich/) - [cheetah vs domestic cat](https://atoneplace.net/animal-vs/cheetah-vs-domestic-cat/) - [cheetah vs ostrich](https://atoneplace.net/animal-vs/cheetah-vs-ostrich/) - [cougar vs domestic cat](https://atoneplace.net/animal-vs/cougar-vs-domestic-cat/) - [domestic cat vs lion](https://atoneplace.net/animal-vs/domestic-cat-vs-lion/) - [domestic cat vs tiger](https://atoneplace.net/animal-vs/domestic-cat-vs-tiger/) - [domestic cat vs leopard](https://atoneplace.net/animal-vs/domestic-cat-vs-leopard/) - [domestic cat vs jaguar](https://atoneplace.net/animal-vs/domestic-cat-vs-jaguar/) - [domestic cat vs snow leopard](https://atoneplace.net/animal-vs/domestic-cat-vs-snow-leopard/) - [domestic cat vs grizzly bear](https://atoneplace.net/animal-vs/domestic-cat-vs-grizzly-bear/) ## Sources - Typical range compiled from manufacturer specifications — At One Place (/about/) - Smithsonian National Museum of Natural History — Smithsonian Institution (https://naturalhistory.si.edu/)
