How Africa’s Rarest Wildcat Uses Rodent Burrows to Raise Kittens
Affiliate Disclosure
Hey fellow impactful ninja ?
You may have noticed that Impactful Ninja is all about providing helpful information to make a positive impact on the world and society. And that we love to link back to where we found all the information for each of our posts.
Most of these links are informational-based for you to check out their primary sources with one click.
But some of these links are so-called "affiliate links" to products that we recommend.
Why do we add these product links?
First and foremost, because we believe that they add value to you. For example, when we wrote a post about the environmental impact of long showers, we came across an EPA recommendation to use WaterSense showerheads. So we linked to where you can find them. Or, for many of our posts, we also link to our favorite books on that topic so that you can get a much more holistic overview than one single blog post could provide.
And when there is an affiliate program for these products, we sign up for it. For example, as Amazon Associates, we earn from qualifying purchases.
What do these affiliate links mean for you?
First, and most importantly, we still only recommend products that we believe add value for you.
When you buy something through one of our affiliate links, we may earn a small commission - but at no additional costs to you.
And when you buy something through a link that is not an affiliate link, we won’t receive any commission but we’ll still be happy to have helped you.
What do these affiliate links mean for us?
When we find products that we believe add value to you and the seller has an affiliate program, we sign up for it.
When you buy something through one of our affiliate links, we may earn a small commission (at no extra costs to you).
And at this point in time, all money is reinvested in sharing the most helpful content with you. This includes all operating costs for running this site and the content creation itself.
What does this mean for me personally?
You may have noticed by the way Impactful Ninja is operated that money is not the driving factor behind it. It is a passion project of mine and I love to share helpful information with you to make a positive impact on the world and society. However, it's a project in that I invest a lot of time and also quite some money.
Eventually, my dream is to one day turn this passion project into my full-time job and provide even more helpful information. But that's still a long time to go.

📰 The quick summary: New research reveals that Africa’s smallest wildcat, the black-footed cat, depends almost entirely on abandoned springhare burrows to raise its kittens, offering scientists a clearer picture of what this rare species needs to survive.
📈 One key stat: 98% of the dens used by black-footed cats were originally dug by springhares, highlighting just how critical this one rodent species is to the wildcat’s survival.
💬 One key quote: “I can’t prove black-footed cats would disappear without springhares, but at this site they would be much more vulnerable,” said Harold Brindley, the study’s lead author and a researcher at the University of Cape Town.
1️⃣ The big picture: Africa’s smallest wildcat, the black-footed cat, is one of the rarest felines on the planet, with fewer than 10,000 individuals remaining in the wild. New research tracking five female black-footed cats in southern Namibia has uncovered a fascinating survival strategy: these cats rely almost exclusively on burrows abandoned by springhares to shelter and raise their kittens. Researchers scanned more than 50 burrows between 2020 and 2021, finding that 98% of the dens used by the cats had originally been dug by springhares, a small endemic rodent. Kittens spend their first six to seven weeks of life in these underground dens, after which mothers begin moving them to a new burrow nearly every night to reduce the risk of predation. Despite being the world’s most efficient feline hunters, these cats are deeply vulnerable, and understanding their dependence on another species is a key step toward protecting them.
2️⃣ Why is this good news: Discovering that black-footed cats rely so heavily on springhare burrows gives conservationists a concrete, actionable insight into what this rare species needs to thrive. Protecting springhare populations and the habitats they share with black-footed cats can now become a focused conservation priority. The study also sheds light on the cats’ behavioral strategies, such as frequently switching dens to protect kittens from predators, which helps scientists better assess population vulnerability. With fewer than 10,000 black-footed cats left in the wild and very few studies conducted on them, each new piece of knowledge significantly strengthens the foundation for future conservation efforts. Understanding these ecological dependencies between species can also serve as a model for protecting other rare carnivores that rely on habitat engineers to survive.
3️⃣ What’s next: Researchers can now use these findings to assess how springhare population trends directly affect black-footed cat survival and reproduction. Conservation efforts in southern Namibia and beyond can prioritize protecting the shared habitats of both species. Further studies tracking more individuals across different sites could help determine whether this dependence on springhare burrows holds across the full range of the species.
