There do seem to be quite a few hedgehogs around who have decided not to hibernate this year – despite being large enough. I suspect most are this year’s youngsters. I have two here. If there is any way you can try to reduce how many sunflower hearts and increase the cat biscuits the hedgehog gets instead, that would be better for it. I’m not sure where the ones here are spending the day either – not in my boxes!
I hope the hog there continues to do well. Good luck.
