It seems that Mr. Jingles owners have allowed him access to his cat door again, and he's wandering the neighbourhood.
He showed up 2 days ago and said hello, got some pets and left again. We were happy to see that he wasn't cooped up in his house any more.
We've seen him every day since then, but he never stays long, he's in to say hello, rub up against us and leave again. The longest we've seen him for it probably five minutes.
It's a huge relief that he's allowed to wander again.
