Last evening, I took this photo of a young hedgehog enjoying a meal of Sainsbury's Meaty Loaf dog food on the patio. The weather is so mild, so it's still active and hasn't hibernated yet!

Thanks, divebuddy; I will investigate "Autumn Juveniles". Frost forecast later next week, so hibernation might be on the cards. I've been feeding a large adult for the past couple of months; maybe the one pictured is an offspring thereof.
Looks like the young 'un survived the Winter - it was seen last evening foraging under the bird feeders (bits of suet, or maybe slugs/snails)). Back to putting out some dog food each evening!
