Remember Tiddles? He's David's on-air correspondent from a variety of events: football matches, local fetes, foreign postings, the lot. He's also a cat. To the untrained human ear it can sound as though David's simply playing a "strangulated meow" effect from a bank of audio clips on a computer - but all cats, even the barely visible Basil, can understand every word.

Well, we're slowly piecing together more information about Tiddles with every appearance. And today I discovered that Tiddles is owned by none other than cricketing legend Geoffrey Boycott!

I got my first clue at 1:30pm, while reading a sports bulletin. Geoffrey, ever one to have an opinion, reckons it's a disgrace that England's cricketers all got MBEs last year, and now they're being humbled by the Aussies. We had an audio clip of him saying as much - and adding that he was going to give his own OBE to his cat, as it meant nothing any more.

Richard, the presenter on air at the time, punctuated this by declaring the cat to be "Tiddles, OBE". Ah-ha, I thought. So that's where he's been all winter! Every since the football season started and David's Saturday show found itself replaced by live commentary, our feline correspondent's headed Down Under with Mr Boycott to watch some cricket.

But I couldn't quite be sure. As has been widely documented, all BBC journalists need at least two sources for their stories these days. Patience was needed.

My lucky break came while driving home listening to Five Live. It's often the case that the sports scripts and clips we get are from the central BBC newsgathering service, which pumps out material to all BBC radio stations. In this instance, the very same Geoffrey Boycott clip had found its way onto the Five Live cricket round-up that evening.

The moment it had finished, Five Live's Russell Fuller declared Geoffrey's cat "Tiddles, OBE". That was uncanny (uncatty?). Why should two radio presenters, on different radio stations, at different times of day, without being prompted, both plump for "Tiddles" as the name of Geoffrey Boycott's cat? Clearly it could only mean one things - it's our very own Tiddles!

My great fear now is that, unable as I am to distinguish Tiddles' insightful analysis from a strangulated-meow sound effect, I don't know what accent he has. If he sounds anything like Boycott, heaven only knows what we've been unleashing on the feline population of Berkshire.

Oh and speaking of cats on the radio - here is a radio station dedicated to cats.

Finally I should make the point that while both presenters went for the oh-so-predictable "Tiddles, OBE" joke, I took it to a new level, announcing that Geoffrey's cat had been elevated to the Order of the British Em-Purr. I thank you.
