(Associated Press) With Apple previewing the next version of its operating system – dubbed Mountain Lion – a crucial question arises: How many more big cats are left for Apple OS X monikers?

According to Wikipedia, Apple so far has used Cheetah, Puma, Jaguar, Panther, Tiger, Leopard, Snow Leopard, and Lion. Could cougar be next? Or the decidedly less menacing Tabby? Strangely, in 2000, it named its beta version of OS X “Kodiak” after the big grizzly bear.

Apple released a 156-company list of the companies that make up its supply chain on Friday. Many of the companies on the list were already identified as Apple suppliers, thanks to gadgets blogs that post “teardowns” that expose the guts of Apple products, but this is the first time the firm has disclosed that information.

The full list, as it appears on Apple’s Supplier Responsibility page, appears below:
