I'm going to find Shamley on the map for us.

John Bradshaw and Sarah Ellis are two of Britain's leading cat scientists.

It should sweep round to the right.

They're on their way to the village of Shamley Green in Surrey to recruit cats for the study.

I think one of the things that will be really interesting about this study is, it's every owner's dream to find out what their cat does as soon as they go through that cat flap.

Well, let's hope it's going to be...their dreams are going to be satisfied, it won't be a nightmare.

The cat sniffing into the butcher's next door and stealing sausages.

There are over ten million cats in the UK.

And the highest density of them are found here, in the southeast of England.
