Rabbit disease
Your various features on rabbiting make no reference to Rabbit Haemorrhagic Disease (RHD),
which seems to be passing under the radar of many in the sporting world, perhaps because, unlike myxy, death happens quickly and rabbits die out of sight underground. According to some sources, it has a 100% mortality rate. In the past a walk with a gun would almost always guarantee a rabbit or two with which to feed the dogs, but for two years now sighting a rabbit has been noteworthy.
