A while back, posted some pics of a hog house I'd had to make for daughter to appease her conscience over stabbing the hedgehog in their compost heap while she was turning it. Hog made a full recovery and uses the house every day. So now had to make a cat-proof feeder for it, as on the advice of the hedgehog specialists, she puts a tray of cat food out for it each night. This is the result; a mixture of some plastic planks left over from a raised bed, bits of plastic soffit boarding left over from their house extension and a small amount of wood, Siberian pine also left over from their extension. Not a thing of beauty, but it worked when tested.
