I found this breed on the internet.
What actully interested me is this name Serengeti, a Wildpark in Africa (featured in NGEO long time before).
Its a cross between Oriental x Bengal. Serengeti is in Pedigree making.
"which until the breed is more established would most likely be a Siamese".. refer http://en.wikipedia.org/wiki/Serengeti_Cat

Interestingly the bengal blood line used is one from many generations weaned from the original genetics of an ALC. So I guess this one is a friendly cat...with a big ears.. look at the length of the tail..
