Save the Scottish Wildcat
No angry tabby or feral the wildcat is a genuine wild species of cat; it was here long before we were and long before the domestic cat had even evolved. Infamously the only wild animal to be completely untameable, even when captive reared, Scottish wildcats may look a little like your pet cat but these are incredibly tough super-predators, sometimes called the Tiger of the Highlands.
Sadly, the wildcat is critically endangered with less than 100 individuals appearing to remain in the wild and barely a handful in the captive breeding population.
