I think chips are a great idea with any pet thats big enough to have one. Anything can happen to paper work and photos. The only down fall is that they only work if someone finds and or turns in you pet to be scanned, if its lost or stolen. If its found (or stolen) and they decide to keep it, give it away or sell it you're pretty much s.o.l. Even if its relocated some time down the road and scanned most people give up and or just don't remember to update the info on the chip. Which is why I think there should also be GPS Chips. I know they have collars for cats and dogs but even those can be lost and or removed . These days we can track cars, cell phones, laptops and what not,..why not our pets.
