Small cat breeds, and the "small" breeds to think twice about
The naturally small and slender cat breeds recognised in the UK, what they are like to live with, and why welfare groups advise against Munchkins and other cats bred for dwarfism.

The short answer
The Singapura is recognised as the smallest domestic cat breed, and the Devon Rex and Cornish Rex are also small, slender breeds. These are naturally small cats, not miniaturised ones. Many ordinary moggies are also smaller than pedigree breeds. Be wary of cats sold as small because of short legs. Munchkins are bred for a form of dwarfism, which Cats Protection and International Cat Care link to bone, joint and spine problems.
Key considerations
- 01The Singapura is recognised by the GCCF as the smallest domestic cat breed.
- 02Devon and Cornish Rex cats are small, slender and very active, with distinctive wavy coats.
- 03Munchkins are bred for dwarfism. The GCCF won't recognise them, and Cats Protection links dwarfism to bone and joint problems.
- 04Size varies between individual cats, and many moggies are smaller than pedigree breeds.
If you would like a cat that stays on the small side, a few recognised breeds are naturally petite. But "small" can also be the result of breeding for unhealthy features, so it is worth knowing the difference before you choose.
Naturally small cat breeds
The Governing Council of the Cat Fancy (GCCF) is the UK's main registry for pedigree cats. These breeds are recognised by the GCCF and are naturally small or slender.
Singapura
The GCCF describes the Singapura as acknowledged as the smallest breed of domestic cat. It lists males at around 6 to 8 lb and females at around 5 to 6 lb. Singapuras have large eyes and ears, and a short, fine, silky coat in an ivory colour ticked with sepia brown. They are known for being curious and lively, and they don't reach full size until around two years old.
The GCCF stresses that the Singapura is not a miniaturised breed, and that breeders shouldn't select for ever-smaller cats. The breed also has a small gene pool, and the GCCF has approved an outcrossing programme to help.
Devon Rex
The Devon Rex has a pixie-like face, very large ears and a soft, wavy coat. The GCCF lists it at 6 to 9 lb and describes it as intelligent, mischievous and highly active. Devons are very people-focused and usually do best with company.
Cornish Rex
The Cornish Rex is slender and elegant, with long legs and a short, silky coat that falls in neat waves. The GCCF lists it at 5 to 10 lb and describes it as sociable, affectionate and playful. Despite being slim, Cornish Rex cats feel surprisingly heavy and muscular when picked up.
What about moggies?
Many ordinary domestic cats, or moggies, are naturally smaller than most pedigree breeds. If you want a small cat, an adult rescue cat whose size and personality are already known can be an excellent choice.
Small cats to think twice about: Munchkins and dwarf cats
Munchkin cats have very short legs because they are bred to keep a genetic form of dwarfism. Cats Protection explains that cats with dwarfism are at greater risk of health problems with their bones, joints and spine, and can develop arthritis and chest problems. It is campaigning for the breeding of cats with dwarfism to be banned.
The GCCF doesn't recognise the Munchkin or any other dwarf breed, and has no intention of doing so. International Cat Care, a veterinary-led charity, says breeding for extreme features, including the short legs of dwarfism, should be actively discouraged because of the risks to welfare.
It is currently legal to own, breed, buy and sell Munchkin cats in the UK. If you already have one, regular vet checks and keeping your cat at a healthy weight will help protect their joints.
Choosing a healthy small cat
- Ask the breeder about the parents' health and any recommended health tests.
- See the kitten with its mother, in the place where it was raised.
- Avoid breeds or individual cats with extreme features, such as very short legs, folded ears or very flat faces.
- Consider an adult rescue cat if size matters to you.
Before you decide
- Can you give an active, playful breed enough play and things to climb?
- Have you asked the breeder about the parents' health and the breed's breeding policy?
- Would a small, adult rescue cat suit you just as well?
- Have you avoided breeds with extreme features that can affect welfare?

No. Small breeds are still normal-sized adult cats, just lighter and slimmer than average. Cats bred to stay tiny can have health problems.
Sources: Singapura
Are Munchkin cats healthy?
Munchkins are bred for dwarfism, which Cats Protection links to bone, joint and spine problems, including arthritis. The GCCF won't recognise the breed because of welfare concerns.

Devon Rex cats are playful, intelligent and very sociable. They suit homes where someone is around for much of the day, and they often enjoy the company of another cat.
