One of the cats ran up into a neighbour's tree sometime on Tuesday morning,

and it was still up there twenty four hours later.
Now, for anyone who ends up getting a cat stuck up a tree (and you live in the UK), the procedure is to wait for 48 hours, call the RSPCA, and they'll call out the fire brigade.
The RSPCA informed me that the fire service won't come out unless the cat has been in the tree for two days, as the cats have a nasty habit of jumping out of a tree in fright when being approached by strange men in uniform. If a cat is still up after two days, it is less likely to jump, so they tell me.
Anyway, this little moggie was meowing continually all night through to Wednesday morning. Faced with having to leave him up there another day before the professionals would turn up, I resorted to trying to coax the cat down with talking, arm waving, and a tin of sardines. Amazingly after a while this started to work, as the cat took a few tentative steps down the branch towards the trunk. Some time later he got up the courage to climb down the trunk of the tree. Finally this cold wet moggie was down to the ground.
5 minutes later and he was acting like nothing had happened. grrr.
