I just noticed a tiny bit of discharge from Sienna's vagina, does this mean she is close to delivery or does this happen throughout the pregnancy? She is sitting in a shelf up in my closet sleeping. She is not meowing or looking like she's in labour. She purrs when I talk to her or pet her though and is really affectionate. How close can she be? For those who don't know the story she is a foster so I have no idea when she got pregnant or when she is due.
