Wildcats bred through the Saving Wildcats project are fitted with GPS collars to map their movements, and it’s fascinating to see their activity, the crossovers between individuals as they find and mark their territories or search for mates. While some cats  are quite local in their movements, others travel astounding distances – one was tracked going all the way from Speyside to Deeside, over Ben Macdui, the UK’s second highest mountain. In all, 46 individuals have been released so far, with very high survival rates and evidence that litters of kittens have been born in the wild.
