I feed mine Spikes semi moist and dry (mixed up) but their favourite is I Love Hedgehogs food which have recently changed their recipe in lieu of recent hedgehog feeding research re mealworms, sunflower hearts and peanuts.
Before hibernation my hubby was spoiling them with chopped chicken which they all loved; but now they seem to prefer the hedgehog food. I have fed them chopped up hard boiled eggs which they have eaten in the past and chopped apple. But these are treats and not something I give them often.
What they all love is a bowl of water – they drink a lot of water 🙂
