"In all nine cases where pedigree information was available, affected cats allegedly originated from the mating of Scottish Fold to cats with normal ears." (臨床案例+某貓舍放射線診斷,九個能提出血統證明的罹病cases都是蘇格蘭折耳混非折耳)
"This article concerns six cats that developed signs of SFOCD. At lease five of them were allegedly the progeny of mating a Fold to non-Fold. A radiographic survey in a cattery suggested that, contrary to contemporary wisdom; this was likely a widespread problem in this breed. " (臨床研究的六個cases中,"至少"五個血統來源是蘇格蘭折耳混非折耳)
作者在conclusions更說 "As all Scottish Fold Cats suffered from Osteochondrodysplasia of some degree, the best solution would be to avoid using fold-eared cats for breeding and instead use Scottish Shorthairs." (所有蘇格蘭折耳都罹患某程度的Osteochondrodysplasia,最好的解決之道是不要用蘇格蘭折耳做繁殖)
