No squirrels here, but yesterday I looked up from my morning coffee cup to see a rock hyrax sitting on the garden wall, not far from the pond. If you've never seen one of these guys, here's a short video of what they look like:
These guys post lookouts, so if you see one sitting there watching you, you know there are more of them. Sure enough, one was climbing over what remains of the back garden fence and another was clambering around in the trees. I tried to get a photo, but as soon as I got up, the lookout gave a whistle and they all vanished down the hillside.
I heard them just outside the garden a few times during the day, but it wasn't until late afternoon that I discovered what they'd been up to: a potted brugmansia near the back garden wall had been completely denuded of leaves. I could have warned them that brugmansia is deadly poisonous, but I have a feeling they were after it for its hallucinogenic properties.
I don't see any around now, so I'm not sure whether they died of the stuff, or lying around their dens tripping out on a brugmansia high. Not rock hyraxes, but stoned hyraxes!
