They do sometimes disappear for no apparent reason but it’s highly unlikely that he just got the hump about the menu and moved out because of it. They can get addicted to the wrong foods like mealworms and sunflower hearts and need to be weened off them but if there’s Spikes out there and they’re hungry they will eat it quite happily so keep putting it out.
They can be unpredictable at this time of year due to the very short nights and also females looking after ankle-biters at home and hunting at strange times so don’t worry, he’s probably still about somewhere. They can seem to vanish for weeks then come back with a vengeance so keep at it with food/water.
Have a check around for fresh hedgehog poo each morning? That’s the best way to gauge activity.
