I was struck by wonder if this was true and I found one site cat mating . My only remaining question is why? All I could find from the previously mentioned website was
Why are they barbed? Anyone know the purpose of this?
Vague recollection from back on the farm here, but I think the barbs create tears in the uterus which is where the various fertilized eggs attach themselves to develop into cat fetuses and eventually kittens. I presume the ‘tear’ makes it somehow easier for the egg to attach.
It’s believed to stimulate ovulation.
Making tears in the uterus would be…difficult. Unless male cats are hung significantly more astoundingly than the males of most species they won’t get anywhere near the uterus.
I remember from somewhere a few years back a report that someone had experimented with smooth glass rods and the gal-cats still yowled. While I’d be less than relaxed if someone were inserting glass rods up any of my works, I assume the kitty cats were not graphically imagining bad things happening with regards to broken glass, and at any rate the report was presented in support of the idea that the yowling does not indicate pain (= no fishhooks on the glass, of course).
As anyone who has pressed down on the base of the tail of a cat in heat can attest, the cat screams and yowls regardless.
You did what?
Peace,

Being a lifelong cat owner, I can say with some authority that, yes, the barbed penis is for stimulating ovulation, and, no, it doesn’t get up into the uterus.
Also, the male cat bites the scruff of the female’s neck, so I hear, and I guess this helps the whole ovulation thing too. I’ve never witnessed cat mating. It doesn’t sound all that romantic, if you ask me.
We begged our dad for kittens, so I had a cat in heat when I was a kid. It was a trip, lemme tell you. They just wander around, padding their hind legs and yowling until you let them out. Then they yowl some more. Then every boy cat within a 200 mile radius comes to your back yard to duke it out. More yowling, of a different sort. Plus snarling, hissing, screaming, and other unpleasant noises.
After all this, she had four kittens, and we gave them all away. That was part of the deal from the beginning, but I still cried when people came to claim them. After the last kitten was gone, and the last sniffle, my Dad said “That’s it, I’m getting that damn cat fixed!”
First, I’m glad you got your cat fixed, even if she DID mate first.
Second, I’m astounded that your cat had such a mild heat. MY queens always make very lewd and explicit suggestions to humans, other cats, and any inanimate object that they might encounter. I brought home a rather sick adult female cat once, and she hadn’t been spayed, and the vet wouldn’t spay her until she recovered. Unfortunately, she went into heat before she recovered. She propositioned my husband shamelessly, no matter how many times he carefully explained to her that he didn’t date outside his species. She managed to instruct our neutered male cat in the Ways of Love (or at least in the Ways of Lust), but he couldn’t rise to the occasion. He managed the neck bite, and the back legs treading, but I don’t think that the relationship was ever consummated, which led the female to be even more frustrated than ever. So I have seen cats ATTEMPTING to mate.
And if I’d had a little kitty dildo available, I would have used it, believe me. Yeah, it’s sort of gross, but a Siamese queen in heat has to be heard to be believed. Whenever a Siamese does something, she has to do it louder and more flamboyantly than other cats. This includes being in heat.
Cats don’t ovulate until they mate. The barbed penis is, as Tengu notes, commonly believed to induce ovulation. If a queen doesn’t ovulate, she will go out of heat, but then she’ll come back into heat in a couple of weeks to a few months (depending on the individual queen’s cycle and on the time of year). It’s far, far better to get Kitty spayed ASAP.
Rabbits also ovulate when they mate, by the way. I have no idea whether or not a buck rabbit’s penis is barbed.
Well, I didn’t want to get into it, but along with the weird thing with the hind legs, she did a fair amount of raising her little cat butt up in the air in an unmistakable “do me” pose. That didn’t stand out in my mind as much as the yowling though. The vocalizations were really the killer. Incessant, loud, tortured "rrrrroooooowwwwwlll"ing until you can’t stand it any more.
Clearly all the boy cats were into it, though.
I’ve owned an unspayed female cat.
There’s definitely a market for cat dildos.

I just noticed that the OP and I posted the same site. The information is the sentence immediately after the one the OP quoted.

Cats mate the same way Klingons do.
