I'll pass. If I lose one of my pets, all of the vets and the shelter will hear from me long before they find it and they'll hear from me regularly until they find it.
Most of the pets that are put down at the shelter are abandoned, not lost. If someone abandones their pet, is the city going to track them down and force them to keep the pet? How will that work?
These are not locator chips, so they will not help anyone find their pet. They only help identify the pets that are found.
A) I don't know if they cause tumors or not.
B) Also, call me crazy, but I don't like the idea of the government mandating microchip implants in anyone/anything. This makes part of me wonder if the next step is mandatory implants in people, because of all of the runaways and kidnapped children, perhaps with the successful pet microchipping cited as supporting research.
C) The city needs to start getting some work done and stop passing regulations that it can't/won't enforce.
