Who have the same problem of stray cats and dogs coming into your house’s compound to ‘finish their business’? Sometimes the garden just smells so awful all thanks to them. But now, we got a new hero to thank. All hail Rick Prescott. No, he’s not the processor chip that will fry an egg. But he’s invented an infrared tracking sentry gun! Ok, this will not kill the stray cats please, but surely they’ll get scared away, so you won’t have to worry about WWF coming and knocking at your front door.
