It's now half way through July in the middle of a heatwave, & we have not seen one single hedgehog this year, we normally see them in our grounds around 10pm every night, & as i'm the gardener here, i often see their droppings around, but nothing at all this year. It's probably due to the long cold spring, & them not having consumed enough food to last them for such a long hibernation.
If anyone reading this has seen any i would love to hear from you.
