Ah, I guess you're right. I've never seen any outside of an LFS, and they're all usually ~1". Just looked up some full grown specimens, and they do seem to get to be a few inches. From what I'm reading, though, Otto cats are very temperamental when being purchased and need to be QT'd for quite some time, as they tend to have internal parasites if they've been wild caught, and they are also notorious for being starved in transit to reduce the ammonia load, and can have trouble picking back up on eating. I may give them a try, though.
