Hi Flatheadwifi
We’ve experienced similar with a neighbours cat who spends most of the night in our garden desperate to eat the food we put out for the hedgehogs. It’s unbelievable the positions it gets itself into – it’s a real contortionist! And a little frustrating as we ourselves have two cats, but they don’t go out at night.
From our experience we kept making the entrance hole smaller and smaller and eventually the cat gave up, but the hedgehogs (and the starlings in the morning) can still easily get in. It’s not a squeeze at all for the hedgehogs.
I can post a picture or point you in the direction of a couple of videos if this would be helpful (and I can work out how to do it!!).
Hope this helps xx
