Burmese cat
In the early 1930s, Dr. Joseph Thompson of San Francisco imported a dark brown female cat from Burma named Wong Mau. At that time in the United States, there was no cat breed similar to Wong Mau. Eventually, Wong Mau was crossed with Siamese. Subsequently, new breed kittens were born that had characteristics like Siamese. This crossbreed type was later developed as the Tonkinese.
