Father-of-two Dave Evans developed an ultra-light GPS which fixes to your pet’s collar and records where it has been.

When the animal returns home the information is downloaded via a USB cable direct to a website which reveals its secret life on Google Earth satellite images.

Mr Evans, 41, said the weatherproof tracker, weighing just 15g, will cost £50 and can be used for cats and dogs.

He said:

Yollo was getting fat even though I was feeding him less and I needed to know what was going on.  Now I know he enjoys chasing chickens at 6am every morning and can see his favourite hangouts.

‘The tracker will provide answers for other cat users if Tiddles is playing away or simply show where they go when they’re out on the tiles.’

Sounds like fun.  Now I wonder if you can use it on husbands…..
