Bloody April: Why don't animals menstruate?

I have been distracted by this kitty-cat:

who gets to have sexytime with this kitty-cat:

Thereby making expensive purebred baby Norwegian Forest Cats. The black stud cat belongs to my boyfriend; he's going to breed once & be snipped, so we're a bit anxious about the whole process. So sorry for yesterday's somewhat pedestrian Wordle post. Today, though, the kitties have me thinking, why don't we notice other animals menstruating like we do?

Humans actually absorb back a darn lot of the bloody uterine lining. And this is what animals do! Why waste that good blood? Imagine being out in the wild & leaving a trail of blood. Not exactly safe if you have predators around. Chimpanzees will menstruate, and apparently dogs can have some type of bloody issue, but it's not exactly menstruation. 


  1. A friend of mine had a "menstruating" dog and she used to put a special pad on her during "her time of month" -- it looked so funny!

  2. I never really thought about that!

    We breed Oriental Shorthairs, so if you have any questions you can shoot me an email or something. :)

  3. Yellowdog Granny:
    She is a beauty! The pic is a little deceptive though. She only weighs about 5 lbs!

    Starre: I will email you. Sienna, the girl cat, doesn't seem to be coming into heat like the breeder said she would.

  4. Reminds me of the Crone, who holds her blood power within. And - the kitties are beautiful!

  5. We were going to breed my Rotweiller and so let her go into heat twice - ugh! We had to put undies on her - she left little blood spots behind. Poor babe. Once her potential mate was found unsuitable, we had her fixed immediately!

    Good luck on the kitty-breeding!

  6. I remember when Auntie tried using doggie pads on her pup years ago. Animals are not meant to wear diapers or pads, lemme tell ya! Related side note, alpacas can absorb an entire cria (baby alpaca; though, obviously not fully formed)!
