The following recently published article talks about making pet micro chipping and registering a pet mandatory in the UK.
Would requiring microchips in pets and owner registration help reduce the number of strays in pet shelters and the cost of boarding and euthanizing them? Certainly, it will increase the number of reunions between pets and their owners. It would also increase accountability in pet owners encouraging them to turn in their pet to a shelter as opposed to abondoning them. When traveling with a pet, microchips are essential to protect your pet should it be lost or separated from you.
Are there further issues as well? How would the program be enforced? Would mandatory micro chipping in domesticated pets mark the start of greater identification in all animals and eventually in humans?
