For three centuries, the Scottish wildcat held on. Through deforestation, persecution, and the slow encroachment of civilisation into its Highland territory, Britain's last surviving wild cat clung to existence — until, in 2019, scientists delivered a devastating verdict: the species was functionally extinct in the wild.
Now, three years after the first captive-bred wildcats were released into the Cairngorms National Park, there are signs that the Highland Tiger may yet have a future. And for the first time, the scientists leading the effort are allowing themselves a cautious, data-backed measure of hope.
A gamble in the Cairngorms
In the summer of 2023, the Saving Wildcats project — led by the Royal Zoological Society of Scotland (RZSS) — released 19 captive-bred wildcats into the Cairngorms Connect landscape. It was the first conservation translocation of wildcats ever attempted in the United Kingdom, and nobody could be certain it would work.
The cats had been raised at a purpose-built breeding centre in a restricted area of the Highland Wildlife Park near Aviemore, where staff trained them to stalk, pounce, and fend for themselves. Each animal was fitted with a GPS-radio collar before release, allowing scientists to track their movements across the vast Highland landscape.
The early results exceeded expectations. A study published in the IUCN's Cat News journal in December 2025 found that all but one of the original 19 cats survived their first 10 months in the wild, with an average body weight increase of 20 per cent — a clear sign the animals were finding food and establishing themselves.
Two cats were later lost — one struck by a vehicle, the other dying of starvation — but the overall survival rate has remained remarkably high. Of the 46 wildcats released across three waves between 2023 and 2025, only four known mortalities have been recorded — a figure scientists describe as exceptional for a carnivore reintroduction programme.
Kittens in the heather
The most thrilling milestone came in 2024, when camera traps confirmed the birth of wild-born kittens within the release area — the first Scottish wildcat kittens born in the wild from a captive-bred population. Seven females produced litters that year, and at least five more gave birth in 2025.
"We're delighted with the results of the restoration programme so far," said Dr Helen Senn, project lead for Saving Wildcats and a conservation biologist at RZSS. "The fact that litters of kittens were born and raised the year after the first wildcats were released is testament to the fact the animals are doing well. It's too early to make long-term predictions, but this is definitely a step in the right direction."
The ghost in the gene pool
Yet for all the optimism, one threat looms larger than any predator or Highland winter: hybridisation. The very characteristic that pushed the Scottish wildcat to the brink — interbreeding with feral domestic cats, which dilutes the wildcat's distinct genetic identity — has not gone away.
The Saving Wildcats team has been working with the charity Cats Protection to trap, neuter, and vaccinate feral domestic cats in the release area. So far, 132 feral cats have been processed — a painstaking effort to create a buffer zone around the reintroduced population.
"We've made huge strides for wildcat conservation in Scotland, and we now have the science and evidence to back up our theory that wildcats can be restored through careful planning, breeding and release," said Dr Martin Gaywood, species project manager at NatureScot. "But uncertainty and challenges remain."
What comes next
The EU LIFE-funded phase of the project is due to end in October 2026, with a second phase planned from November. Future releases may be more strategically targeted — introducing males into female-heavy areas to boost genetic diversity and further reduce hybridisation risk.
The project has also been reaching into the communities living alongside the wildcats. Local schools have named released cats. Predator-proof poultry coops have been provided to farmers affected by the cats' return. And a feature-length documentary, Clinging by a Claw, narrated by Outlander star Sam Heughan, is screening across Scotland.
Feasibility studies for wildcat reintroductions have even begun in England and Wales — a sign that what is happening in the Cairngorms may one day reshape the landscape of conservation across the whole of Britain.
For now, somewhere in the ancient Caledonian pine forests, a female wildcat is raising her kittens in the heather. She has never known a cage. She is, in every sense that matters, wild.
And that, say the scientists, is worth daring to hope for.
