VetStar Day 1

A 1.5-year-old spayed female cat presents with a 7-day history of vocalizing, rolling, and allowing a male neutered cat in the household to mount her. The cat has gone through one similar episode 1 month ago. She otherwise has been behaving normally and has no other health problems. You performed an ovariohysterectomy on the cat at 3 months of age. You perform vaginal cytology which shows some cornified epithelial cells but is inconclusive. You measure serum lutenizing hormone of 0.2 ng/ml (normal for an ovariectomized female is >1 ng/ml). Which of the following is the most appropriate course of action?
一只一岁半的已绝育母猫最近7天以来不断嚎叫，打滚，愿意被附近一已绝育的公猫爬跨。这只猫一个月前也出现过类似的情况。除此之外她没有出现任何健康问题。你在这只猫三月龄时给她做过子宫卵巢切除术。这只猫的阴道涂片上可见一些角化上皮细胞，但无法作出判断。其血清促黄体激素为0.2ng/ml（已绝育的母猫正常值是>1ng/ml）。以下哪项是接下来最适合的做法？
