urethra (2 photos: male, female):

Male cat's urethra begins directly below (inferior to) the urinary bladder and ends where the penis ends.

Female cat's urethra begins directly below (inferior to) the urinary bladder and then anastomoses (joins) with the vagina, forming the urogenital sinus (unique to the female cat).

ductus deferens (3 photos):

ductus deferens (right tube & left tube) where they anastomose with the urethra of the male cat, forming a thickened area: the prostate gland.

urogenital sinus (female cat ONLY):

  Urogenital sinus is formed by the anastomosis (joining of vessels) of the vagina and urethra of the female cat.

prostate gland (male cat ONLY):

The prostate gland is located INSIDE the anastomosis of the 2 ductus deferens (plural = ductus deferentes) with the urethra of the male cat.
