Singapura Singapuras are affectionate, people-oriented cats that also enjoy the company of other animals. Singapuras are very playful, highly energetic, and remain so well into adulthood. In fact, they are downright pests, always underfoot, curious and involved in their surroundings. Their single-minded determination can be exasperating, especially when the object they desire is the pen you are writing with. They love warmth and comfort and make ideal house cats, with no interest in going outside. Their short, sleek coat sheds very little. These cats are intelligent and stubborn, and impossible to keep off the kitchen counter (they like to perch up high). That, in a nutshell, is the smallest domestic breed of cat.
