Whilst trying to remove one of those horrible saw grass plants a couple of years ago (the type that shreads you to ribbons if you happen to pass by too closely) I thought I would cut it down close to the ground first before trying to dig out the root ball. I first tried pruning shears, no chance, so I tried a wood saw, much more effective. Now, about halfway through, I thought I heard something Growl. So I paused, looked about, the dog was inside, so carried on. Then another growl, louder this time, so I stopped again, parted the leaves of the plant and peered inside. Staring up at me was a very, very angry mummy Hedgehog and her 4 or 5 little pink baby hogs! I was a out halfway across their nest and a out an inch and a half above them with the saw blade! So I covered them back over and left well alone for a few weeks. Racked with guilt for disturbing them and almost decapitating an entire hog family, I left them food out for a few nights as way of an apology.
Who knew hedgehogs could growl?
