Well, they're not really "wild" as in you find them out in the wild. But they're of wild breeds instead of domesticated breeds. Just wild cats tend to be more expensive.
If they were wild, as in feral. They'd probably end up starting their own community that would probably fail due to the lack of being able to breed, but, they'd end up more bestial and not really fun to play. Afterall, sometimes, out of despiration [or protection] humans end up on wild cat's dinner plate.
But, the two breeds mainly have comsmetic and some mental changes.
But nontheless, they're all born and raised by the company who created them. :)
As well, it's hard to find a wild bred cat at a store, they're usually at the open "breeding farms."
