It’s perfectly true too…I have some stills from the security cameras somewhere and will dig them out.
It happened a few years ago now at a small but busy hospital in the Highlands of Scotland. In the wee small hours the door alarm was triggered but when staff went to let in whoever it was who needed help there was no one there.
Later, when the CTCV camera was checked a pair of otters could clearly be seen at the glass door, standing on their hind legs, obviously trying to get in. They made off when the alarm sounded. A cute little story but even stranger was to come. The next morning the cleaners spotted a mess on the glass. On closer inspection it turned out to be bloody otter paw prints.
Had this pair of animals come to the hospital looking for help? Who can tell?
