The breed standard of the modern Siamese calls for an elongated, tubular, and muscular body and a triangular head, forming a perfect triangle from the tip of the nose to each tip of the ear. The eyes are almond-shaped and light blue, while the ears are large, wide-based, and positioned more towards the side of the head.
Siamese are usually very affectionate and intelligent cats, renowned for their social nature. Some Siamese are extremely vocal, with a loud, low-pitched voice that has been compared to the cries of a human baby, and persistent in demanding attention. These cats are typically active and playful, even as adults, and are often described as more dog-like in behavior than other cats.
Siamese cats occasionally suffer from depression or separation anxiety if left alone for long periods of time, and it is for this reason that Siamese cats are often bought in pairs so that they can keep each other company.
