Kayla the cat

One of the more interesting physical features of this species is its external genitalia. Males have an unusually long penis and baculum, reaching to between its forelegs when erect. The glans extends down the shaft about halfway and is spiny except at the tip. The female Fossa exhibits transient masculization, starting at about 1-2 years of age, developing an enlarged, spiny clitoris that resembles a male's penis. The enlarged clitoris is supported by an os clitoridis, which decreases in size as the animal grows.
