My Jules is DEFINITELY part oriental breed...what, I'm not sure, but a local vet who breeds several cat breeds has told me Havanese, others have told me everything from Bombay to Oriental Shorthair to Siamese. Whatever he is, he's not telling, lol! But he's got the long lean body shape, the triangle face, big ears, is VERY talkative, and is very eager to please.
That being said, he was thrown out. He was found in a cardboard box at maybe three weeks old, and was lucky to have been found. I've personally known him since I could fit him in my hand. He's now a lean mean, 9lb cat all muscle, is VERY smart, uses his paws to investigate everything, and loves everyone even though he is absolutely devoted to me.
When you bring an oriental type breed into your home, be prepared to stay on your toes...they are SMART! Jules even knows how to open and close doors, and knows sit and shake paw. I never walk him without a harness...while he is very attached to me, I could never forgive myself if something happened to him. He loves everyone, especially the elderly and dogs...he even gets along with other cats he's just met (after a hiss or two, lol). He talks to me CONSTANTLY, with little peeps and strings of almost bird-like noises. He's also very athletic...like this cat will jump over 7 feet high from a standstill just to catch a wand toy (he actually hit the ceiling fan once, lol!).
I guess with all this said, is that I got a mixed breed oriental rescue. He's really given me a lot to think about when it comes to cats, but I wouldn't change him one bit...he's my baby boy!
