If you are not sure if your cat is a mix breed or not, there are a few things you can look out for. Siamese cats are usually a light tan or brown color with a darker muzzle, legs and tail. They typically have almond-shaped eyes that can range from blue to green, and their ears are often large and pointed. They also tend to have a sleek, long body and a short muzzle. If your cat has any of these features, then it is likely a Siamese mix. Additionally, Siamese cats are known for their vocal nature and outgoing personalities, so if your cat has a loud, talkative, and friendly demeanor, it could be a Siamese mix.
