Weighing in at only two kilos, the rabbit is the lurchers' favourite quarry. Birds of Prey, wild cats, badgers, foxes, stoats, ferrets, dogs and humans. Yes, rabbits are definitely a prey species, and it is clear that the domestic dog has a much easier predatory life than it's wild counterpart. Lurchers also take other prey. Incredibly fast, sensible enough to plan escape routes, back track to lay false scent trails, and protected by a complete field of vision, the hare is only a catch for the most skilled or, occasionally, the most persistent.
Foxes also prey an hares, as do any other flesh eaters who are fast or persistent.
And like hounds, some lurchers also hunt foxes. Competing for many of the same meals, all canids are natural competitors with the genus vulpes. It really is a dog eat dog world. Carnivores compete, and conflict often ends in death, it is Natures way of ensuring the balance. Those who think of the fox as the 'uneatable', can find no justification for it's pursuit, and consider it 'unnatural' for one carnivore to hunt another, should look beyond their own views for the answer.
