Ugh. I feel like a horrible pet owner.
Our local animal shelter had an open house with a microchipping clinic-- they brought in a vet to do the clinic, so I wasn't too worried. It wasn't so much the cost savings, as it was that they use the same registry that we already have River with.
Robin did very well with all the people and dogs and chaos, considering. I guess some old lady kept trying to pet her while my husband was walking her away from the fray. Robin gave a low growl, and the lady kept trying to pet her. My husband pushed her hands away and told her to stop, to which the lady replied, "Oh, she's just scared." Well no crap, Sherlock.
Anyway, that was all fine. We asked to go in a side door so as not to walk through the crammed, ridiculous mass of people and dogs. The thing was so, so poorly run. Anyway, Robin was scared of the vet and the tech, and had to be held down to get the chip in. I heard a bit of a growl. I felt so bad.
My husband took her out and I stayed with the cat to get her chipped. I was afraid I'd made a huge setback in her stranger danger. But when I came out the door, some random woman had her sitting and doing tricks.
Regardless, I shouldn't have taken her there, I'll never do that again, I feel terrible.
