折耳貓如何避免骨頭的問題？

[大敦寵物醫院]

brian : 親愛的戴醫師

一直對折耳貓有興趣
找人問問題中我查到您
折耳貓是一種骨頭的突變，有可能造成骨頭發育的問題

摘錄讓我覺得需要注意的地方
Little was known at this time about the natural mutation which results in the folded ear. In the early 1970s Dr. Oliphant Jackson, an English geneticist, released a report stating that the breed carried a bone problem. The decision was made, the report stated, that changes and the vital use of outcrosses were needed to restore the original health of Folds. About this time, x-rays of Folds started showing bone lesions. According to Dr. Jackson’s report, there had been no previous mention of associated skeletal deformity before the ’70s. Scientists and breeders wondered whether these were being caused by in-breeding early in the history of the Folds rather than by the Fd gene itself.

Originally, many Folds had foreshortened tails which were inflexible. Dr. Rosemond Peltz, who served as the first genetic consultant for the American Scottish Fold breeders, offered the opinion that “in generations to come the undesirable defect may be diminished by extremely careful breeding.” With the knowledge from the Jackson study, breeders began to use more outcrossing and the gene pool increased. This produced longer, more flexible tails and the bone lesions and foreshortened tails began to disappear. In January 1976 the stud book closed to all outcrosses except the American Shorthair and the British Shorthair.

他上面意思是說要避免骨頭的問題
一方面是要跟英短及美短交配外
一方面就是注意小貓「尾巴」是否比較短及「沒有彈性」
所以這是要注意的嗎？
是否假如小貓尾巴沒有彈性長大有可能有骨頭的問題？

大敦寵物醫療中心院長戴更基醫生 : 1.不是的,他的意思是,折耳的缺陷是會遺傳的,但是如果將折耳貓和外來貓咪交配,骨頭的問題會逐漸消失,因為這種基因是隱性的,但是又要維持折耳的狀態,滿足折耳迷的需求,所以從1976年一月起,除了和英國短毛貓或是美國短毛貓交配以外,限制折耳貓和其他品種的貓咪交配.

2.尾巴短及不易彎曲是折耳貓的骨頭問題,未來要避免就要依照上述的方法來繁殖,並不是說尾巴沒有彈性長大就有可能有骨頭的問題
