Hi Daffydill,
I wouldn’t take the lack of bedding as proof they are not using the houses. Hedgehogs have thick fur under their prickles and so often don’t need to use bedding in the warmer months especially as most hedgehog houses are already cosy and well insulated. I’ve even seen them napping in the feeding station with zero bedding and every appearance of comfort. I’ve not seen mine using bedding all summer either, not even a few dead leaves. So don’t be disheartened! It’s great they can potentially sleep under the shed as well. The more potential nest sites, the better.
