There’s a recurring joke in my household, usually delivered with a weary look from my darling Samantha after a long afternoon wrangling our two epic (read: chaotic) kids, that the gap between pregnancies is the only thing keeping the gears of sanity turning. When we had our kids, I remember hearing that breastfeeding acts as a natural contraceptive. Whether that’s a rock-solid medical fact or just wishful thinking by exhausted parents everywhere, it’s a concept that mirrors something fascinating happening right now out in the Londolozi bush.
The Nkoveni Female and her litter of three, of which the only surviving cub, is the Shingi Male.
Londolozi's most viewed leopard and prolific mother. This gorgeous female has raised multiple cubs to independence.
Because we’ve recently had two of our most well-known leopard females return to mating condition and have cubs, and the stories of how they got there couldn’t be more different.
For human women, the return to fertility after childbirth is largely driven by one thing: whether or not she’s breastfeeding. When a mother nurses, the sustained release of prolactin — the hormone responsible for milk production — suppresses the hormonal cascade that would otherwise trigger ovulation. This is called lactational amenorrhea, and it works reasonably well as a short-term natural contraceptive. Stop nursing, and within weeks, the body typically starts cycling again. It’s fairly clean, fairly predictable, and fairly straightforward by comparison to what a leopard goes through.
Because for a leopard, stopping lactation is just the beginning.
The Nkoveni Female and Shingi Male as a cub feeding on an impala carcass.
When a leopard cub starts eating meat, usually around three to four months old, the milk bar closes, and the prolactin brake is released. Theoretically, a mother could fall pregnant again when her cub is barely eight months old. But she almost never does. Why? Because her body is still running the full marathon of raising a teenager, and it knows it.
There are two main “brakes” keeping her from double-booking the den. The first is what you might call the grocery bill problem. Hunting for a growing cub is a relentless caloric burn. She’s feeding herself and subsidising a cub that is eating more by the week. Her body, governed by hormones like leptin that act as a kind of fuel gauge, essentially sends a memo to the reproductive system: we can’t afford a new litter while we’re still running on empty.
The second brake is stress. A mother leopard is in a permanent state of high alert — lions, hyenas, nomadic males, the whole cast of predators who would happily kill her cub given half a chance. The sustained cortisol load from that vigilance actively suppresses the reproductive axis.
It’s her body’s way of saying: not now.
Alarm calls of impala gave away the position of the Tinxiya female as she was dragging the newly killed impala lamb to a nearby suitable tree.
It’s only once the cub starts to separate, spending days away, making its own kills, needing less and less, that both those brakes ease off simultaneously, and the switch finally flips.
The Shingi Male seemingly finds some ‘morbid comfort’ in using his duiker carcass as a pillow in the branches of a dead Tamboti tree. His mother, the Nkoveni Female (his mother) had in fact caught the duiker the night before, gone through all the effort to find her sub-adult cub and led him back to the meal only to be barred from feeding on any of it by the young male. a clear sign that he’s close to being forced into independence.
The Nkoveni Female is a textbook example of this playing out exactly as it should. She’s done a sterling job raising the Shingi Male, who, true to form for a male cub, hung around a little longer than his female counterparts tend to. Free meals are hard to give up. But eventually, independence came. The Shingi Male started dominating his own kills and started covering a larger tract of Londolozi.
The Shingi Male walking through the long grass at sunset.
The grocery bill finally dropped, the stress of motherhood gradually lifted, and she was recently seen mating with the Maxim’s Male. Fingers crossed that the next chapter of her lineage is already underway.
And then there’s the Ximungwe Female, whose road back to this point was anything but textbook.
She attempted to raise a cub, and somewhere along the way, managed to break her front left leg. What followed should, by any reasonable logic, have ended in tragedy.
A three-legged leopard with a dependent cub in a landscape full of lions and hyenas is not a survival story anyone would have written. But she didn’t abandon the cub. She kept hunting. She kept the cub alive through the entire recovery, limping through the bush on three legs and somehow making it work. It was one of those things you watch with a mix of awe and discomfort, knowing the odds and watching her defy them anyway.
Sadly, after she’d recovered and was back to full fitness, the cub disappeared. We don’t know exactly what happened. These things rarely come with a clear answer, but it was gone. And here’s where the biology becomes almost brutal in its efficiency: without the physical presence of the cub, without the demand to feed and protect it, the hormonal suppression vanished almost immediately. Her body didn’t grieve. It recalibrated. She was seen mating shortly after, and we believe she gave birth to two new cubs around the 4th of January this year.
There’s something worth noting here. One last thing that separates leopards from us when it comes to getting pregnant: they are induced ovulators. Unlike humans, a leopard doesn’t just release an egg and hope for the best on a regular cycle. The physical act of mating is what actually triggers ovulation. Which is why you’ll see a mating pair going at it up to four times an hour for days on end.
Samantha pointed out that this sounds exhausting. I agreed and quietly decided not to elaborate.
So whether it’s the textbook route, a cub raised to independence, a mother’s body gradually released from the metabolic and hormonal load, or the hard route, a litter lost and a body that resets almost overnight, the outcome is the same. The brake releases, the switch flips, and a leopard gets back to the business of securing the next generation.
The bush doesn’t wait around. And apparently, neither do they.
Thanks for that insight. Always interesting to get more facts that explain things in nature.
You are welcome, Jos.
Hi LGR. Thank you so much as usual for putting up such a interesting blog. As we know the nearly 14 year old Nkoveni female has raised her single male offspring from her litter of 3 that she gave birth to just over 2 years ago, but as she was seen mating with the massive jumbo sized Maxim’s male a few weeks ago, it will be so interesting to see if their many matings were and are successful or not. She hasn’t had as many litters of cubs as her elderly mother, the elusive Mashaba female had when she was considerably younger, but she raised pretty much double the number of cubs that her mum managed to raise successfully. As the lovely Nkoveni female will be 14 years old in August, I’m in no doubt, and so are you probably, that this new litter that we’re hoping she’s busy and hopefully conceiving successfully will be her last litter that she’ll have before she’s totally infertile just like her mother. Won’t it? The litter that we are hoping that she will soon give birth to there, will possibly make it litter number six that she would have produced in her lifetime.
The Shingi male, though the sole only survivor from his mum’s old litter, is so very fortunate to have survived cubhood and all the way to independence. As he is now a fully independent young male just starting to fend for himself, let’s hope that he doesn’t get caught and killed by lions like his two litter mate sisters did.
When the last of his two sisters was so very sadly killed by lions just over eighteen months ago, it was a very smart move on his part that he saw the lions coming towards him, his mum and sister and quickly climbed a tree to get out of the way. I think his mum joined him as well, but his sister wasn’t at all fortunate.
So let’s hope that he is very careful and vigilant in his own lifetime of independence and adulthood as he goes about patrolling his own territory or hunting for food. I also hope he’ll know what to do when hunting and there could be unseen danger in the very same area. He will so need to watch his back regularly.
As for the nearly 11 year old Ximungwe female, well as I’ve said before that we know she’s raised 2 handsome and elusive single male adult cubs from her first and second litters to independence individually and successfully, and bearing in mind that her third & fourth litters failed to reach that stage sadly, let’s hope that she is much more successful and lucky in raising her 2 new current cubs all the way to independence there as well. As her cubs are a few days away from been 4 months old and would have grown in size and confidence a lot more, have you now been able to get a good and close enough look at their rear ends to see what gender the cubs are yet at all, or is it still a little bit to early to tell? It might not seem important right now, but as you know all to well, I’m just very interested to know what they both are.
She has, just like her older sister, done a very good and impressive job of getting both of her cubs this far in their lives that they have got to now already.
I hope she continues to be successful in keeping with if her cubs very well concealed and hidden when she’s either out hunting for food or patrolling her territory in the weeks and months ahead to come and go. She will need to watch out for any unwanted danger in the same area, and I know she wouldn’t leave her cubs alone and vulnerable if she saw or sensed danger prowling about nearby.
Though not the most successful, but she is one of your land’s experienced leopard mothers that you’ve known there. If she ever saw danger in the form of another leopard, then wherever she is hiding her cubs either on the ground or in the safety of a tree top, she probably didn’t the tree like a shot and either fight of or chase of the rival leopard that will have posed a threat to the cubs there.
Just like a adult territorial male, I don’t think a mother leopard would take very well and kindly to having trespassers thinking of threatening her cubs while they’re still young and vulnerable. Do you think she would have been more than likely to have chased or fought it of and well away? How many years have you been a ranger there at Londolozi for mow altogether in total so far? You sure must have seen a lot of drama play out in the wilderness throughout your time both good and bad, happy and sad.
What is the latest new/updates on the elderly Mashaba female there so far? I haven’t seen her mentioned in a blog for quite a long period of time now unfortunately. Have you? I hope she is still alive and well, as I’d love to see her in a blog and/or video clip again very soon one day. Wouldn’t you? She has got to have first prize for been the oldest leopard over there in beautiful South Africa.
Hope to hear from you shortly.

Robert, as always, thank you for such a detailed and passionate comment.
A few quick updates: the Nkoveni Female is indeed getting on in years and this next litter, if successful, will almost certainly be one of her last. Fingers firmly crossed for her. The Ximungwe Female’s cubs are doing well and growing fast, gender confirmation is still a little tricky at this stage but we’re working on it and will update as soon as we can get a good look! As for the Mashaba Female, she has not been seen for quite some time and so could be that she is no longer around. Will absolutely share any news the moment we have it.
Hi Sean and Samantha! These two sisters (the Nkoveni and Ximungwe females) showed a peculiar resilience, it seems, like their mother, the Mashaba female, whom I still hope to get fresh news about… they symbolise the strength and power of motherhood. Leopards are unbelievable, they manage to survive and protect their offspring against all odds… I still wait to see if once Leopards will manage to stay together, say, two sisters…. very unlikely, but they are such adaptable creatures, you never know… thank you for such beautiful portraits of such amazing mums!
The Mashaba lineage really is something special with generations of remarkable mothers. As for two leopards choosing to stay together, I wouldn’t hold your breath! But you’re right, they are endlessly adaptable and have surprised us before. Never say never in the bush.
Hi Sean, thanks for this vital information about the leopard mothers. I have great respect for them and they are my favorite animals in the bush. You wife Samantha is a very wise lady and beautiful. Being a working mother at that as well and having two toddlers around the house is hard work. Leopardess have so much working against them in the wild where there are always predators lurking around to kill the cubs. I take my hat off to Nkoveni, Ximungwe females for their hard work raising their cubs and protecting their cubs till the end. Be
Thank you Valmai, I’ll pass that on to Sam, she’ll appreciate it! And yes, full respect to both of these females. The odds stacked against a leopard mother are extraordinary and they just get on with it without complaint.
Thank you, Sean, for this detailed information!
As always, done with a wonderful balance between scientific insight and hilarity, as it is your unique style! 🙂
Thank you!
Thank you Alina, that balance is exactly what I’m going for, so really glad it came through. Appreciate the kind words!
Well explained, Sean. Loved the human analogy – and Samantha’s reaction to mating frequency! I’ve wondered about that myself!
Thanks so much, Mary Beth. Glad the analogy landed, and thanks for reading!
Having spent nearly a week at Londolozi in April 2025, I’ve been addicted to your Virtual Safari and your blog. You do great work. Today’s wordsmithing tickled me: “…keeping her from double-booking the den.” Brilliant!
Thank you for all you do, Sean!
That’s so great to hear, Aaron — welcome to the addiction! Really glad you enjoyed the visit and that the virtual safaris have kept the bush alive for you since. Thanks for the kind words!
I suppose humans have it easier as we don’t routinely have twins or triplets like the leopards? !
Say hi to Sam from me.
Good point. Will pass on your hello, and I am sure she will send her regards in return.
FYI – not all women stop ovulating whilst breastfeeding (sadly after only a few weeks my cycle was in full regular swing…and I only nursed, no supplementing, for a year w/ my first born)!
Of course there are always exceptions to the rule. The biology is never as clean as we’d like it to be, and clearly your body didn’t get the memo.
Haha! Clearly!!😂🫶🏽
Thanks Sean for this information about why female leopards don’t begin the mating process again, once their cub(s) are weaned. I always look forward to learning something new or hadn’t considered.
That’s exactly what keeps me writing these, Denise, if one person learns something new, it was worth it. Thanks for reading!
Thanks, Sean, for the explanation of how leopard’s cycles work. This is really interesting.
You are welcome, Christa. I am glad you enjoyed it.
The Ximungwe Female is indeed an especially brave and resilient leopard mum. To manage as a three-legged leopard prevented by a serious injury to use all her limbs to care for her cub is an incredible survival story .It was really with a mix of awe and discomfort that everyone, I think, followed her story. And because of this, it was really so very sad that all her efforts were in vain in the end because her cub died.
I do hope that she will be luckier this time. Such a great mother!
