Well the difference may be health related because I got the first frilled from a girl who had rescued it. It could be that she is stunted. She is 2 years old and just an itty bitty thing. She is short and has a more rounded stocky body. The new guys are 1 yr old and long and slender and about twice as big as her. Are there pics somewhere of Auusie vs NG frilled so I can look?
