Old tech re-used
The hedgehog hotel that I DIYed a couple of years ago needed it’s inner wall bolstering too keep out the inquisitive cats of the neighbourhood. An old shelf bracket and a couple of old gutted VHS tapes that seem made to slot in that rigid groove make for a handy damp proof modular inner wall that stops those cats getting to the extra food we leave out for our annual nocturnal garden hedgehog visitors. One day I might even get a wireless web camera in there who knows.
