Smallest Cat Breeds by Weight
The Singapura is often called the smallest cat breed in the world. Here are the petite cats by the numbers — and why small doesn't mean delicate.
How we built it
Computed automatically from the breed-standard adult-weight range on each PetGrit cat profile, ranked by the lowest top-of-range weight (so the breeds that stay smallest rank first). Weights are parsed from the same figures the profiles display.
If a pocket-sized, eternally kitten-like cat is the dream, a few breeds stay genuinely small into adulthood. This ranking is computed live from the breed-standard adult weight on every cat profile in our dataset, ordered by how light each breed stays at the top of its range. The Singapura usually takes the crown as the smallest, with several fine-boned Oriental and Rex breeds close behind. Just remember: a small cat is still a full cat in every way that counts.

Sources & method
- PetGrit cat breed dataset — breed-standard adult weight per breed — Drawn from breed-standard sources cited on each profile.
- Breed-club standards for the Singapura and other small breeds — Context for typical adult sizes.
The short version
- The Singapura is the smallest cat breed by weight, often staying around 4–8 pounds, with the Devon Rex and several Oriental breeds close behind.
- Most of the smallest breeds are fine-boned Oriental or Rex types — small in frame but big in energy and personality.
- A small cat still needs full enrichment and vertical space, and its lighter frame makes even minor weight gain significant.
Frequently asked questions
What is the smallest cat breed?
The Singapura is widely considered the smallest cat breed, with adults often weighing just 4–8 pounds — females can be as little as 4–6 pounds. Despite the tiny size, Singapuras are muscular, active, and famously busy and curious. Other small breeds include the Devon Rex and several slender Oriental-type cats.
Are small cat breeds good for apartments?
They can be, but for the right reasons. Small breeds take up little space and are easy to handle, which suits apartments — but the smallest breeds (Singapura, Devon Rex, Orientals) also tend to be highly active and people-oriented, so they need plenty of vertical space, play, and company rather than just a small footprint. Match the energy level, not just the size, to your home.
Are 'teacup' or 'dwarf' cats real?
Be cautious. Unlike the naturally small Singapura, 'teacup' and 'dwarf' cats are usually the product of deliberately breeding for extreme smallness or short legs, sometimes by crossing short-legged Munchkins. That practice is associated with skeletal, joint, and mobility problems. A genuinely small breed like the Singapura is healthy; a cat marketed as unnaturally tiny for a premium price deserves real scrutiny.
