I see this was an older poll thread that I already voted in (voted no pets chipped). I guess I never put in a post explaining why.

In my area; some of the vets, some of the humane societies, and NONE of the animal control offices will scan cats!! I don't see why dogs get preferential treatment in this area.

I'm not going to pay that money for 7 cats, put them through being tranquillized, poked, then 3 days of hissing at each other just to not have them be scanned if they are picked up anyways.

Until every area of animal handling scans every single animal, I'm not changing my position on it.
