3. Devon Rex Cat

With their large ears, slim bodies and soft, curly coats, Devon Rex cats weigh only around 5 to 10 pounds (2.3 to 4.5 kilograms). These tiny, playful cats cats love to stay close to their humans, making them ideal for pets.

4. Cornish Rex

The Cornish Rex is another lightweight breed, characterized by its wavy coat and slender frame. They often weigh between 6 and 10 pounds (2.7 to 4.5 kilograms) and are known for their high energy levels. These cats are among the most affectionate and active of the smaller breeds.

7. Somali Cat

Somali cats, often described as miniature versions of the Abyssinian, have a slender build and bushy tails. They weigh between 6 and 10 pounds (2.7 to 4.5 kilograms), and they love climbing — so having cat trees or shelves is a must for Somali cat owners.

8. Sphynx Cat

Their compact, muscular bodies make Sphinx cats one of the smallest breeds. Weighing around 6 to 12 pounds (2.7 to 5.4 kilograms), they love being the center of attention.
