Jumper, an Oreintal shorthair?

Perhaps some of you remember my rescuing two cats from the Arkansas City animal shelter back in June. One was a dilute calico (Callie), and the other is a tan-colored male (Jumper). They were so tiny when I brought them home with me. Now, Callie is a little larger than her littermate brother, Jumper. Jumper is a small sized cat with a long neck large ears, a wedge- shaped head , and very short hair. He is about 24" long now including his tail. His color is a fawn-type. I went through the CFA's breed profiles, but couldn't find any cat that looks like him. He appears to be an Abyssinian, but does not have an Aby's personality traits. I think the closest breed that appears like Jumper is an Oreintal short-hair. Does any one have an idea what his breed type is?

My guess is he is mixed. Now, oriental shorthair could certainly be in that mix.
