Whilst giving my lawn a mow, movement from the pond caught my eye and spotted a hedgehog having difficulties getting out. It had managed to get itself caught between a sunken pot and the edge of the pond and couldn't haul itself out (I'm very conscious of hog safety and thought I'd covered all safety issues by having slopping edges and a beach - first incident since installing pond over 18 months ago). Hauled the poor chap out and he's now on a towel, on a heat pad, in a cat box with a dark blanket over the box to keep out light. At first he was shaking, so immediate concern was getting him warmed up. That seems to have stopped now, but concerned with what I need to do next. Tried to ring a couple of wildlife animal rescues near me, but no answer (it's Sunday). Also, my vets are closed except for emergency. I'm sure he's going to be OK, but wondering if I should take him to rescue place tomorrow, or leave him to go free once it gets dark this evening and when his mates come into the garden. Should I wait till tomorrow evening to make sures he's eaten something? Happy to take whatever advice. I live in West Surrey - so if anybody knows any local rescue contacts, please let me know.
