I made my feeding station out of a 32l plastic under-bed storage box as I have found the low height stops cats trying to get in. I cut the entrance hole in a short end and then if you put the food bowls at the other end a cat can’t put a paw in to drag the bowls out. I have my camera trap on a tripod so I can see that cats try, but are soon defeated. A couple of bricks on the lid stop cats/the wind taking the top off. It’s not the most attractive thing in the garden, but the hedgehogs don’t mind and it’s easy to clean!
