Hi Hedgie Lover
You might find the water bowl was empty because they tipped it over. They are very good at that! I’ve even seen one trying to tip over an 11 inch diameter plant saucer with water in it – presumably to see if there were any tasty morsels underneath. It didn’t manage to tip it over but did move it a bit. Must have been stronger than it looked – all that practice pushing other hogs around – it was a male. And don’t be persuaded that your cameras capture everything that happens – they don’t. Hogs actually drink quite slowly – tiny mouths – so it doesn’t always appear that the water has gone down by much.
But, yes, why go round the water when you can go through it!
