子宮頸未能適當擴張或開放導致難產。可能因先天異常、纖維化或功能障礙。需剖腹產取出胎兒。
Queens are induced ovulators; pseudopregnancy is less common than in dogs. Pyometra can occur after exogenous progesterone administration. Mammary hyperplasia (fibroadenomatous change) is common in young intact or progestin-treated queens and is self-limiting after OHE.
