NC but regular poster. I just went out to the garden and saw something on the lawn that looked a bit like a hedgehog. At first I thought it was a ball of dead grass, but then saw it covered in bluebottles. Looked closer and it's definitely a dead hedgehog 
Thought it was weird, but as I glanced further down the lawn I saw THREE more, perfectly still, and covered in flies.
I assume(d) that possibly it was a little family that had been poisoned, as it looks like they've just dropped dead on their walk across the lawn. But then I found a dead rat, ripped in half with entrails everywhere but the top half intact and it's clearly a youngish rat, not a mouse. The hedgehogs don't look injured, no blood or wounds.
Also found two halves of an eggshell (like stolen from a nest, not the supermarket!) in two completely opposite ends of the garden.
What the actual fuck. What's killed all the wildlife!? I have a cat but she's not really a hunter, ignores hedgehogs and if she did manage a rat she'd just leave it intact and not shred it to bits.
I do have pics but didn't want to upset people, but I can post them.
Any ideas what has been on a murderous rampage in my garden? Nothing like this has ever happened before.
