Chris Keeney's 'PetCam: The World Through the Lens of Our Four-Legged Friends' allows us to see from the perspective of our beloved pets.
If you want to know where your pet is coming from, you have to walk a mile in their shoes (so to speak). Keeney uses the PetCam, a digital camera that can be attached to a collar, to give us some insight on how our dogs, cats and teacup pigs experience their surroundings. The device takes pictures at pre-set intervals, which you can then access from a memory card stored inside.
You can help give your pet a voice by documenting the world as they see it, or merely browse Keeney's book to get an idea.
