My brother in law just got a savannah cat. It is part African cerval (SP), part Egyptian cat. At 2 years it will be full grown. Huge cat, its a meat eater and supposed to be on a leash if outdoors. This cat is about 3 months old and can jump over the couch. The other day we caught it on the counter so we brushed him off, so he jumped to the ground, about 6 feet from the counter, it is amazing. The guy he bought it from says its momma will jump up and land on the top of an opened door.
Savannah cats are pretty awesome. They're just so expensive.
