Frequently asked questions

How much does a cat weigh?

A healthy adult domestic cat weighs 3.5โ€“5.5 kg, depending on breed and build. Males are typically larger than females. Maine Coons (largest breed) reach 7โ€“11 kg. Singapuras (smallest breed) stay around 2 kg. We use 4.5 kg as the average.

Is my cat overweight?

Vets define cat obesity as more than 20% above ideal weight. For most breeds that means anything over 6 kg is worth checking. Look at body shape rather than just the scale โ€” you should be able to feel ribs easily but not see them.

How many cats can you legally own?

No legal limit in most of the UK or US, but local councils sometimes set "hoarding" thresholds (often around 5โ€“10 animals). The famous "cat sanctuary" of Lynea Lattanzio in California houses over 600 rescued cats โ€” at 4.5 kg each, that's 2,700 kg of cat.

How many cats do you weigh?

The average adult domestic cat weighs 4.5 kg. A 75 kg adult equals approximately 16.7 cats โ€” though only one of them will tolerate sitting on you at a time.

What goes into a cat\'s weight

Cats have a fairly narrow weight range compared to dogs because domestic cat breeds vary much less in size than dog breeds. The largest cat breed (Maine Coon) tops out around 11 kg; the smallest (Singapura) is around 2 kg. By contrast, dogs range from 1 kg (Chihuahua) to 90+ kg (English Mastiff). Cats simply weren\'t bred for the size variation that dogs were.

Lean body composition is around 70% of a cat\'s mass; the rest is fat, with healthy adults sitting at 15โ€“25% body fat โ€” higher than the equivalent percentage in humans because cats are obligate carnivores adapted to feast-and-famine eating patterns.

Cat trivia

  • The heaviest cat ever recorded weighed 21.3 kg โ€” about 4.7 average cats in one body. Guinness no longer recognises heaviest-cat records to discourage overfeeding.
  • The world\'s tallest living cat (a Savannah named Fenrir) stands 47.8 cm at the shoulder โ€” taller than many small dogs.
  • There are roughly 500 million domestic cats globally. That\'s 2.25 billion kg of total cat โ€” enough to outweigh every human in Tokyo, twice.
  • Cats sleep 12โ€“16 hours per day on average. Over a lifetime, that\'s roughly 70% of their existence asleep.
