Over the years, I’ve tracked countless reports of mystery cats across Texas—from the Pineywoods to the borderlands—and every now and then, a sighting pops up that really grabs my attention. That happened again recently with reports coming out of Seguin, Texas, where residents have taken to social media to share stories of a large, black feline being called a jaguarundi roaming near homes and fields.
Some are saying it’s a jaguarundi—a small wild cat once native to South Texas and long rumored to still exist in isolated pockets. And honestly, I can see why people would think that. The descriptions match up: long-bodied, dark-colored, with a tail nearly as long as the body itself. It’s the kind of profile that some say matches a jaguarundi.

But before we jump to conclusions, let’s take a breath.
I’ve been studying these kinds of sightings for decades, and while I don’t doubt the sincerity of the witnesses, I always encourage a cautious approach. Jaguarundis haven’t been officially documented in Texas for quite some time. That said, I do believe there are some in Texas but there is another cat with a similar appearance.
In my own work, I’ve coined the term “black longtail” to describe what some people mistakenly call “black panthers” in Texas and elsewhere. The cats I am talking about obviously aren’t melanistic leopards or jaguars but they also don’t neatly fit the normal domestic house cat category. They’re something else. I’ve collected dozens of firsthand accounts of black, long-bodied cats that defy easy classification.
So could the Seguin cat be a jaguarundi? It’s possible. Could it be a black longtail? Just as likely. I’ve even considered the idea of large black domestic cat hybrids or escaped exotics playing into these stories.
The reality is, we don’t have conclusive photographic or biological evidence yet. What we have is an intriguing sighting that fits a pattern I’ve seen before.
If you’re interested in digging deeper, I’ve covered the jaguarundi mystery in detail on my YouTube channel in the video: Black Panthers In America: The Jaguarundi?
I also explore the wider phenomenon of “black longtails” in this video: A Look At The black Longtail

If you’re in the Seguin area and have seen something similar—or have clear photos or videos—I’d love to hear from you. These mystery cats continue to fascinate me, and every report helps build a broader understanding of what might be out there.
Whether it’s a surviving pocket population of jaguarundis or another chapter in the black longtail mystery, one thing is certain: Texas still holds wild secrets. And I’ll be here, doing my best to uncover them.
