羊粪为啥是一球一球的

粪便得形状取决于动物肠道得形状以及解剖结果。

同意上面宠物医生曹小壮的看法,但是除了肠道性状外,好像还有别的因素。参考这个网页:The Straight Dope: Why do some animals have pellet poop? 下划线是我加的。“So, to recap, the #1 factor is the colon, #2 is the rectum (and possibly sphincter), and #3 is the diet and how it\u0026#39;s digested (that is, those factors which determine the consistency of the feces itself).”翻译过来就是1.结肠 2.直肠(也许还有相应的括约肌)和3.饮食以及其消化方式。
