What kind of BREED do my cat have in her???

Hi, I have a beautiful cat named Shorty Blackwell. When she was born, she was all white, but had a faint tint of grey on the tips os her ears and her tail. Gradually these colours on her ears and tail grewe darker. Now she is almost 5 yrs. And she has dark markings around her bottom legs, a grey and black tail, grey and black ears, a mix of grey & black throughout her back and sides, and around here nose, is an orangy, yellow colour. Also she has Bright blue eyes. If anyone knows, please drop me a line!!!!:)

siamese kittens are born pure white and then develop their color points over the next three weeks after birth, getting more and more color as they age. normally, their bodies darken with age, but usually not into multi colors on their bodies. most siamese mixes are solid black, but the white at birth and the blue eyes definitely sound siamese. you may have a mix, doesn't sound like a purebred siamese.
