I'm a little confused- human or feline. If the former - consider she might have an imperforate hymen. A good gyno will be able to sort this. "Anatomic anomalies
Consider anatomic anomalies that can be confused with imperforate hymen in the differential diagnosis. These anomalies include the following:
* Acquired labial adhesions * Obstructing or partially obstructing vaginal septa (longitudinal or transverse) * Vaginal cyst * Vaginal agenesis (Mayer-Rokitansky-Kuster-Hauser syndrome) with or without the presence of a uterus or functional endometrium * Androgen insensitivity syndrome (testicular feminization)
Frequency
Imperforate hymen is likely the most frequent obstructive anomaly of the female genital tract, but estimates of its frequency vary from 1 case per 1000 population to 1 case per 10,000 population. Heger et al examined 147 premenarchal girls with a mean age of 63 months to collect normative data on genital anatomy; an imperforate hymen was found in only one patient (<1%) and hymenal septa were found in 3 (2%).1
Imperforate hymen usually occurs sporadically, but a handful of cases have been reported to be familial.
