From Savanna to Sofa: The Fascinating Evolution of the House Cat

By Kristen Levine, cat care expert

Why does your cat meow at you constantly, but almost never at other cats? Why does that purr sometimes sound less like contentment and more like a demand? And why, after thousands of years of domestication, does your cat still occasionally drop a dead lizard on your pillow like it’s a gift?

Ask my cat Max about that last one. He was an indoor-outdoor cat who used to bring me lizards as “presents.” Unwelcome ones, LOL.

I put these questions, and plenty more, to someone actually qualified to answer them: evolutionary biologist Dr. Jonathan Losos.

I’d had the pleasure of interviewing Dr. Losos once before, on the Pets Add Life podcast, and he was such a fascinating guest I had to bring him back for round two, this time focused entirely on where our cats came from and why they act the way they do.

Meet Dr. Jonathan Losos, Author of The Cat’s Meow

He even created a freshman course called “The Science of Cats” to lure students in with something they loved, then sneak in a real evolutionary biology education.

That class became the seed for his book, The Cat’s Meow: How Cats Evolved from the Savanna to Your Sofa.

His goal wasn’t to add another cat book to the pile (there are already plenty of those). He wanted real scientific authority behind it, explaining how we actually know what we know instead of repeating internet folklore. Eventually, even though he never planned on becoming a “cat scientist,” he became one anyway.

How Did Cats Evolve From Wild Predators to House Pets?

I challenged Dr. Losos to explain the entire evolution of cats in under a minute.

He pulled it off in 45 seconds flat: the ancestor of every house cat alive today is the North African wildcat, and if one wandered into your backyard, you probably wouldn’t think twice. You’d just think, “huh, interesting-looking cat.” That’s because cats haven’t changed much physically. The real evolutionary story isn’t about how they look. It’s about how they learned to tolerate, and eventually love, being around us.

Here’s the short version.

About 10,000 years ago, when humans started farming and storing surplus grain, those granaries attracted rodents, and rodents attracted cats. Not every wildcat was bold enough to wander into a village, but the bold ones ate well, had more kittens, and passed that boldness down the line. Humans noticed the benefits and started being nicer to the friendliest cats, letting them inside, feeding them, petting them. The cats that tolerated us best did even better, and the cycle repeated until we ended up with the furry roommates snoring on our couches today. In other words, cats didn’t get domesticated so much as they domesticated themselves, on their own terms, which honestly tracks.

In addition to an all encompassing discussion about evolution, I also got a chance to ask him a few other questions too!

Why Do Cats Meow, Purr, and Knead?

Meowing is basically a trick cats invented specifically for us. Adult cats don’t really meow at each other. The only real exception is kittens meowing to their mothers. So every time your cat meows at you, they’re using a baby behavior that just happens to work great on humans.

Purring was the part that genuinely surprised me. Researchers have identified two distinct purrs: the soft, contented one you hear when you’re petting a relaxed cat, and a second, more insistent purr, the one you hear when a cat is winding between your legs while you’re opening a can of food. Audio analysis revealed that this second “solicitation purr” contains a frequency that closely resembles a human baby crying. Since we’re biologically wired to respond to that sound, cats may have evolved this purr specifically to hijack our attention. Sneaky. Once I heard the recordings myself, I could hear it too.

As for kneading, it’s likely a leftover kitten behavior. Kittens knead their mother while nursing to stimulate milk flow, and cats simply never grow out of it. So when your cat kneads you like bread dough at 6 a.m., take it as a compliment. They’re telling you they feel safe.

Why Does My Cat Bring Me Dead Animals or Toys?

This is where Max comes in. Every indoor-outdoor cat owner knows the feeling: you open the door and there’s a “gift” waiting, and it’s not the kind you can return. Dr. Losos admitted this is one behavior science hasn’t fully cracked.

The leading theory is that your cat sees you as a hopeless hunter and is trying to teach you, the same way she’d teach her own kittens. Sweet in theory, less sweet when you’re the one finding a lizard on the welcome mat. Other theories suggest cats may be storing food or simply showing off, but honestly, we don’t fully know.

Why Does My Cat Suddenly Bite Me While I’m Petting Them?

This one is on us, not them. Cats communicate a lot through subtle facial cues, ears, whiskers, body tension, that most of us simply don’t notice. They also get overstimulated by petting, same as anyone would if a friend wouldn’t stop patting their head. The bite rarely comes out of nowhere from the cat’s side. It’s a signal we missed a few steps earlier.

---

Why Do Some Cats Get Along and Others Don’t?

Cats are more social than they get credit for. In places with abundant food, free-living cats form cooperative groups of related females who raise kittens together, groom each other, and even help during births. The only other cat species known to do this is the lion, in prides.

Cats who grew up together tend to stay friendly, while strangers are more likely to see each other as a threat at first, which is part of why vets often recommend adopting two kittens from the same litter.

Meet Nelson and Archie, Dr. Losos’s Own Cats

Nelson, who just turned nine, taught himself to fetch, dropping a cashmere glove at Dr. Losos’s feet one day and looking up expectantly. Dr. Losos assumed this made Nelson a genius, until he learned roughly 20 percent of cat owners report the same thing.

Then there’s Archie, whose tail curls left every single time it’s up, never right, even in kitten photos. No scientific explanation. Sometimes the best discoveries in evolutionary biology are the ones you can’t fully explain, and honestly, same with our own cats.

What Was the Most Fascinating Era in Cat Evolution?

Dr. Losos took me back 30 million years, to the very first cat fossil ever found, which already looks unmistakably like a cat. From there, two major outliers emerged: the cheetah, built for speed, and the saber-toothed cats, which appeared 20 million years ago and were the dominant feline for most of that span, still roaming North America as recently as 10,000 years ago, right as the first humans arrived.

What Does the Future Hold for Cats?

Dr. Losos sees two paths ahead. Feral cats are adapting quickly to extreme environments, from scorching Australian deserts to snowy Tasmanian mountains. Meanwhile, he floated an idea for the future of breeding: purposefully developing cats better suited to modern indoor life, with less drive to hunt and roam.

Talking with Dr. Losos again reminded me how much we still don’t fully understand about the cats sharing our homes, and how much fun it is to learn alongside a scientist who clearly loves them as much as we do.
