Scottish Wildcat - Felis silvestris silvestris No feral or farmcat, the Wildcat is a true wild species of cat; it was here long before we were and long before the domestic cat had first been bred by ancient farmers. Unique to Britain, and now only found in Scotland, the Scottish Wildcat is currently classified as an isolated island population of the European wildcat, Felis silvestris silvestris (Felidae)
There is a picture of Princess Victoria ("Toria"), daughter of Edward VII & Queen Alexandra (1868-1935) holding a cat on the royal yacht (see picture). I don't how significant this is. It does indicate that a royal personage kept a Siamese cat. The picture was taken in about 1914.
